Left Margin Command 5-13

Right Margin Command
The Right Margin command sets the right margin to the right edge of the specified column. ?&a#M #
Logical Page right bound Current left margin - Logical page right bound
The maximum right column is located at the right edge of the logical page (the HMI setting defines the distance between columns, which thereby defines the maximum number of columns on the logical page). If the value field specifies a column which is greater than the right edge of the logical page, the right margin is set to the right edge of the logical page. If the value field specifies a column less than the left margin, the command is ignored. Margins represent a physical position and once set do not change with subsequent changes in HMI. If the cursor position is to the right of the new right margin, the cursor is moved to the new right margin.
To set the right margin to column 45, send: ?&a45M
5-14 Page Control Commands
Clear Horizontal Margins Command
The Clear Horizontal Margins command resets the left and right margins. The left margin is set to the left edge of the logical page (column 0) and the right margin is set to the right edge of the logical page. ?9
Clear Horizontal Margins Command 5-15

Top Margin Command

The Top Margin command designates the number of lines between the top of the logical page and the top of the text area. ?&l#E #

= Number of lines

1/2 inch down from top of logical page- Length of logical page (Other values ignored)
1 If logical page length is <inch, then the top margin is set to top of logical page.
The Top Margin command is ignored if the value field (#) is greater than the current logical page length or if the current VMI is 0 (VMI defines the distance between lines of text). Receipt of a Top Margin command resets the text length according to the following equation:
The top margin represents a physical position and once set does not change with subsequent changes in VMI or line spacing. The vertical cursor position for the first line of print is determined by the current values of the top margin and VMI using the following equation:
The default cursor position is not located at the intersection of the top margin and the left bound of the logical page (refer to Figure 5-5). The cursor is actually positioned down 75% of the VMI distance (0.75 VMI) from the top margin. This positions the cursor at the relative base line position of a character cell for correct character positioning.

HT - Horizontal Tab

Moves the current active position (CAP) to the next tab stop on the current line. The tab stops are at the left margin and every 8th column between the left margin and the right bound of the logical page. If the new horizontal position crosses the right margin, the new horizontal position is set to the right margin. If the current HMI value is 0, the command is ignored.
Horizontal Cursor Positioning Control Codes 6-9
Vertical Cursor Positioning (Rows) Command
This Vertical Cursor Positioning command moves the cursor to a new line in the same column position. ?&a#R #

= Number of Rows

NA 32767 to 32767 (valid to 4 decimal places)
A value field (#) with a plus sign (+) indicates the new position is downward from and relative to the current cursor position; a minus sign () indicates the new position is upward from and relative to the current cursor position. No sign indicates the new position is absolute from the top margin. The top position, defined by the top margin, is 0 and the bottom position is determined by the bottom of the logical page. Note Since the top margin can be changed using a printer command, the physical location of the point (0,0) may change. This affects the cursor position on the page. If a request is made for a location outside the printers logical page, the current active position (CAP) is moved to the appropriate logical page limit.

6-10 Cursor Positioning

Vertical Cursor Positioning (Decipoints) Command
This Vertical Cursor Positioning command moves the cursor to a new position along the vertical axis. ?&a#V #
NA 32767 to 32767 (rounded to the first decimal place)
A value field (#) with a plus sign (+) indicates the new position is downward from and relative to the current cursor position; a minus sign () indicates the new position is upward from and relative to the current cursor position. No sign indicates an absolute distance from the top margin. The top position, defined by the top margin, is 0 and the bottom position is determined by the bottom of the logical page. Note Since the top margin can be changed using a printer command, the physical location of the point (0,0) may change. This affects the cursor position on the page. If a request is made for a location outside the printers logical page, the current active position (CAP) is moved to the appropriate logical page limit.

7-10 Fonts

Internal Fonts
Internal fonts are those fonts that are provided with the printer. Both internal bitmap and scalable font formats are provided. Internal bitmap and scalable fonts and symbol sets for current models of HP LaserJet family printers are listed in Chapter 2 of the PCL 5 Comparison Guide. Font and symbol set listings for earlier printer models can be found in the Users Manual for each printer.

Special Effects

HP PCL 5 printers allow you to create special effects when printing characters. These effects are achieved through the use of the print model feature, or through the use of HP-GL/2 vector graphics (refer to Chapter 13, The PCL Print Model or to the HP-GL/2 information in Chapters 17-23). The print model provides a simple means for printing patterned or shaded characters using the printers predefined cross-hatch/shading patterns, or user-defined patterns. HP-GL/2 vector graphics provide the additional ability to print characters in any direction (angle) on a page, and to print outlined characters. HP-GL/2 also allows anisotropic (non-linear) scaling of scalable fonts which produces characters that are stretched in one direction.

Internal Fonts 7-11

7-12 Fonts
Several characteristics identify a font (as described in Chapter 7, Fonts). Font characteristic selection commands, described in this chapter, are used to specify the desired font characteristics for printing. Commands are included for the following characteristics: symbol set, spacing, pitch, height, style, stroke weight, and typeface family. The printer maintains a font select table in its operating code that contains the characteristic values of the current font. Whenever the printer receives a font select command (escape sequence) specifying a new characteristic value, the printer records that characteristic in the table. After the table is updated (receives new characteristic values), and text is ready to be printed, the printer performs a font select. The printer searches the available fonts and scalable typefaces to select one that matches (or most closely matches) the characteristics as listed in the font select table.

9-2 Font Management

Temporary vs. Permanent Fonts
Once downloaded, a font is automatically designated as temporary. A temporary soft font is deleted from user memory during a printer reset or when a Typeface List, a Font Printout or a self-test is performed from the printers control panel. A soft font can be designated as permanent to prevent the printer from deleting it during a printer reset. A soft font is designated as temporary or permanent by referencing its ID number and using the Font Control command (refer to Font Control Command later in this chapter). Note Both temporary and permanent fonts are deleted from user memory whenever the printers power is turned off. Switching printer languages (personalities), changing resolution, or changing the Page Protection setting also deletes temporary and permanent fonts from user memory in some printers (refer to the appropriate printer Users Manual for specifics). An existing font is deleted when a new font with the same ID number is downloaded. The new font replaces the existing font (whether temporary or permanent).

Deleting Fonts

There are several mechanisms provided by PCL font management that delete soft fonts from user memory. These include commands to delete all soft fonts, all temporary soft fonts, or an individual soft font by reference to its font ID number (refer to the Font ID and the Font Control commands described on the following pages).
Temporary vs. Permanent Fonts 9-3

Font ID Command

The Font ID command is used to specify an ID number for use in subsequent font management commands. The ID number of a font can be used to select the font for printing (refer to Font Selection by ID in Chapter 8).

= ID number

The font ID number is used during subsequent soft font downloads, selections or deletions. The factory default font ID is 0 (if no Font ID command is sent, an ID of 0 is assigned). Note The font number assigned by the printer and used from the printers control panel is not the same as the ID number assigned using the Font ID Command.
To specify a font ID number of 1, send:

E C*c1D

9-4 Font Management

Font Control Command

The Font Control command provides mechanisms for manipulating soft fonts.
= 0 - Delete all soft fonts 1 - Delete all temporary soft fonts 2 - Delete soft font (last ID specified) 3 - Delete Character Code (last ID and Character Code specified) 4 - Make soft font temporary (last ID specified) 5 - Make soft font permanent (last ID specified) 6 - Copy/Assign current invoked font as temporary (last ID specified)

N/A 0 - 6 (values outside range are ignored)
If the primary or secondary font is deleted, a new primary or secondary font is selected automatically from the remaining fonts.
To remove all soft fonts from user memory, send:
To remove only those soft fonts that are temporary, send:
To delete the soft font with an ID of 1, send:

*c1d2F

Font Control Command 9-5
To delete the character p (112 decimal) in a bitmap or bound scalable font with an ID of 1, send:

*c1d112e3F

(A space is printed in place of the deleted character. Also, the EC*c#E Character Code command used in the above sequence.112e., is described in Chapter 11.) To make the soft font with an ID of 2 temporary, send:

*c2d4F

To make the soft font with an ID of 2 permanent, send:

*c2d5F

To make a copy of the currently invoked (selected) font, with an ID of 9, send:

*c9d6F

The Copy/Assign font control feature can be used to copy either ROM or RAM fonts into RAM assigning them ID numbers. Note When the currently selected font is a scalable TrueType ROM font, E *c#d6F assigns a font ID number, but makes no copy of the font C in RAM. Any attempts to download or delete characters within the font are ignored. An attempt to delete the font merely results in the loss of the ID number.

9-6 Font Management

Font Management Example
This example illustrates several typical font management operations. It assumes a bitmap soft font is stored and available on an MS-DOS based hard disk. 1 Set the font ID number to 2:

E C*c2D

Download a soft font file using the MS-DOS COPY command with the /B option: COPY /B filename PRN Note that the soft font is associated with font ID 2.
Make the soft font permanent to prevent its deletion during a printer reset:

E C*c5F

Designate the permanent soft font as primary:

E C(2X

Font Management Example 9-7

Unbound Scalable Fonts

Prior to introduction of the HP LaserJet IIIP printer, a downloaded scalable font was restricted to a single symbol set. Now scalable fonts with no symbol set affiliation can be downloaded. These new fonts are called unbound fonts. To download unbound fonts, the PCL Font Header for Intellifont Unbound Scalable Fonts or the Format 15 Font Header for Scalable Fonts (TrueType) must be used (see Chapter 11).

10-10 User-Defined Symbol Sets

Symbol Map (Array of UI)

The symbol map contains a list of symbol index numbers. This list identifies symbols for the symbol set. (Refer to Appendix D in the PCL 5 Comparison Guide for a MSL and Unicode symbol indexes.) The symbol map pairs (maps) a character code to a symbol index number. The range of character code numbers (paired with symbol index numbers) is the range from the First Code through the Last Code fields in the header. The first symbol index number in the Symbol Map field is mapped to the character code whose value is that of the First Code field; the second symbol index number is mapped to the First Code + 1 character code; the third symbol index number is mapped to the First Code + 2, etc., through the last symbol index number, which is mapped to the value in the Last Code field. The number of symbol index characters in the array must match the number of character codes in the range, First Code through Last Code. If no printable symbol (symbol index number) is associated with a given character code (as with codes 128 through 160 of Roman-8), the corresponding entry in the Symbol Map should be 65535 (FFFF Hex).

11-6 Soft Font Creation

Use the Font ID command to designate a unique ID number prior to the download of a font header. If an existing font is already associated with this ID, the existing font is deleted upon the download of the font header. Unless otherwise specified, inappropriate values in a font header field invalidates the font download process; a font is not created and the associated font data is discarded. Intellifont scalable font formatting also requires the Intellifont Scalable Typeface Format document, which supplements the information provided here. For information on how to obtain this document, refer to Related Documents in the front of this manual. The figures that follow illustrate the font header formats for the various font classifications. The individual fields for the font headers are described following the figures.
Although some LaserJet printer models do not use all of the data in the font header and thus ignore many of the fields, a font creator should use valid values in all of the font header fields. This ensures font compatibility across the LaserJet printer family and with future printers, which may use these fields. Those font header fields identified as reserved should be set to zero.

11-74 Soft Font Creation

A Macro is a group of PCL and HP-GL/2 commands and/or data created by the user that is downloaded and stored in the printer. Once stored in the printer, a macro can be invoked upon request (using the assigned macro ID number), using a single command. When printing letters, for example, which include a company letterhead, the letterhead is repeated for each letter. This letterhead can be created as a macro and stored in the printer. Thus, whenever the letter is printed a macro command, sent to the printer, initiates the command sequence to print the letterhead.
HP-GL/2 commands are not supported within macros on all HP LaserJet printers. Refer to the PCL Feature Support Matrix in Chapter 1 of the PCL 5 Comparison Guide for specifics. Macros eliminate the need to download the same information repeatedly, thus saving transmission time. However, the trade-off is that they consume user memory. If memory usage is a concern, a possible solution might be an HP custom macro cartridge. Custom macros can be written and stored in ROM (read only memory), such as font-type cartridges or SIMM modules. When ROM-based macros are installed in the printer, they become available for selection. There is no need to download the macro and no user memory is consumed.

12-2 Macros

Macro Creation
Designate a unique identification (ID) number prior to the definition of a macro using the Macro ID command. This number is assigned to the macro. If a macro is already associated with this ID number, the previously existing macro is deleted from user memory during the definition of the new macro. Subsequent macro operations are accomplished using the macro ID number. A macro is created in the printer in several steps. First, the start macro command is sent to the printer to indicate the start of a macro definition. Next, the printer commands, control codes, and data that constitute the macro are sent to the printer, in the intended order of their execution. Finally, the End Macro command is sent to the printer to indicate the end of the macro definition
Table 12-1 Assign ID Number Start Macro Definition Macro data Macro ID command (EC&f14Y) assigns a unique identification number (14) to the macro. Macro Control command, EC&f0X, indicates the following commands and data are to be stored as a macro. Escape sequences, control codes, HP-GL/2 commands and text required to perform the desired operation.
Macro data Stop MacroDefinition Macro Control command, EC&f1X, identifies the end of the macro data (definition).

To invoke a macro, send the Macro ID command with the ID number of the macro, then send the Macro Control command with a value field of 2, 3, or 4 (EC&f2X, EC&f3X, or EC&f4X). This performs the macro in the specified mode: Execute (value field=2), Call (value field=3), or Overlay (value field=4). Refer to the following section Macro Invocation for a description of these modes.

Macro Creation 12-3

Macros occupy a portion of user memory. The number of macros that can be stored simultaneously in user memory is limited only by the amount of available user memory.

Macro Invocation

There are three ways to invoke a macro: execute, call, and overlay, using the Macro Control command. When a macro is executed, it begins performing its commands using the current modified print environment. Changes made to feature settings during macro execution are recorded in the modified print environment; these changes are retained upon completion of the macro execution. When a macro is called, it begins performing its commands using the current modified print environment. Before the macro is performed, the current modified print environment is saved. Changes made to feature settings during a macro call are recorded in the modified print environment; however, these changes are not retained upon completion of the macro call. The modified print environment that existed prior to the macro call is restored. When a macro is enabled for automatic overlay, its execution is the final operation each time a page is printed. Before the macro is performed, the current modified print environment is saved and replaced with the overlay environment. The overlay environment is a combination of the user default and the current modified print environments. Changes, made to feature settings during macro overlay, are recorded in the modified print environment; however, these changes are not retained upon completion of the macro overlay. The modified print environment that existed prior to the macro overlay is restored. Note HP-GL/2 commands are not supported within macros on all HP LaserJet printers. Refer to the PCL Feature Support Matrix in Chapter 1 of the PCL 5 Comparison Guide for specifics.

12-4 Macros

The overlay environment consists of the current settings for the following features with the remainder of the environmental features set to their user default values: Table 12-2 PCL CONTEXT: Page length Page size Orientation Registration Paper source Number of copies Cursor position stack
HP-GL/2 CONTEXT: Current Pen Position Hard Clip Limits Logical Page Boundaries Line Attributes Refer to Chapter 3 for descriptions of environments. Note The current active position (CAP, or cursor position) is not part of the modified print environment. Therefore, the cursor position is not saved when a macro is called, nor is it restored upon completion. The Push/Pop Cursor Position command can be used to save and recall a cursor position. Scaling Points Soft Clip Window Fill Attributes
Temporary / Permanent Macros
During its definition, a macro is automatically designated as temporary. A temporary macro is deleted from user memory during a printer reset. A macro can be designated as permanent to prevent the printer from deleting it during a printer reset. A macro is designated as temporary or permanent by reference to its ID number, using the Macro Control command described later in this chapter. Note Temporary and permanent macros are removed from user memory whenever the printers power is turned off. Temporary / Permanent Macros 12-5

Deleting Macros

There are several mechanisms provided by PCL macro control for explicit deletion of macros from user memory. These include commands to delete all macros, all temporary macros, or an individual macro by reference to its macro ID number, using the Macro Control command described later in this chapter. Both temporary and permanent macros are deleted from memory whenever the printers power is turned off.

Macro ID

The Macro ID command specifies an ID number for use in subsequent macro commands.

&f#Y

=Macro ID number = 0 = 0 - 32767

# Default Range

This number is used in subsequent macro operations. The factory default macro ID is 0.
To establish a macro ID number of 5, send:

&f5Y

E C * c # W [pattern data]
=Number of pattern data bytes = 0 = 0 - 32767 (values outside the range are ignored)
The value field (#) identifies the number of pattern data bytes that follow the User-Defined Pattern command. In addition to the binary pattern data, there are eight bytes of pattern descriptor (header) information included in this pattern data. The format for a 300 dpi resolution header is shown in Table 13-3, below. Table 13-3 Byte 8 User-Defined Pattern Header (300 dpi resolution) Continuation (0) Reserved (0) LSB-0

With the introduction of the LaserJet 4 printer, user-defined patterns can be printed either 300 or 600 dpi resolution. X Resolution and Y Resolution fields have been added to the header information included in the previous header. The format for the new header is shown in Table 13-4, below.

The Master X and Master Y Resolution fields can be used to specify 600 dpi resolution for a pattern originally designed at 300 dpi. However, a pattern which was designed at 600 dpi is not available for selection at 300 dpi resolution. Patterns are identified by some value (ID number). This is the current pattern ID number. If the Pattern ID command is not used to assign an ID number to the user pattern, the existing (current) pattern ID value is used. If a pattern is already associated with the ID, that pattern is replaced with the new pattern.

Format (Byte 0)

This field, byte 0, must be set to 0.

Continuation (Byte 1)

This field, byte 1, must be set to 0. (This byte is for future printer support and does not currently provide any continuation operation.)

Pixel Encoding (Byte 2)

This field, byte 2, should be set to 1. (This byte is reserved for future printer operation.)
User-Defined Pattern Command 13-17

Reserved (Byte 3)

This field, byte 3, is not currently used and must be set to 0.
Height in Pixels (Bytes 4 and 5)
This field, bytes 4 and 5, identifies the number of rows (height) of the pattern.
Width in Pixels (Bytes 6 and 7)
This field, bytes 6 and 7, identifies the number of pixels (width) of the pattern.

E *r#S C

# Default
=Width in pixels of the specified resolution = depends on raster presentation mode when presentation mode is 0, width = width of logical page - left graphics margin when presentation mode is 3 then width = dimension of logical page along paper length - left graphics margin = 0 to (logical page width left graphics margin)*
Greater values default to the (logical page width left graphics margin).
This command allows you to implicitly tell the printer to pad raster rows that are not specified for the full raster width with zeros. Unspecified data maps to either white or transparent depending on the source transparency mode. When a Transfer Raster Data command is received that specifies a row of data that is longer than the raster width, the data that extends past the raster width is clipped. This command is ignored after the Start Raster Graphics or Transfer Raster Data commands, until the next End Raster Graphics command. Note Only raster data appearing within the intersection of the logical page, the printable area, and if set, the raster width and height is printed. Data outside the intersection is clipped.
Raster Width Command 15-13
Figure 15-8 Maximum Raster Width
Start Raster Graphics Command
The Start Raster Graphics command identifies the beginning of the raster data and also specifies the left graphics margin.

E C*r#A

=0- Start graphics at default left graphics margin X-position 0). 1 - Start graphics at current cursor position (current X-position). = 0 = 0, 1 (values outside the range default to 0)
A value of 0 specifies that the left graphics margin is at the default left margin of the page (X-position 0). A value of 1 specifies that the left graphics margin is at the current X-position. In presentation mode 3, the location of the left graphics margin varies depending on the orientation. Once a Start Raster Graphics command is received by the printer, raster graphics resolution, raster graphics presentation mode, raster height, raster width, and left raster graphics margin are fixed until an end raster graphics command is received.

15-14 Raster Graphics

The number of status responses a printer can buffer varies from printer to printer. The HP LaserJet 4 printer can store 5 responses. Refer to the PCL 5 Comparison Guide for printer specific information. A status response is returned to the printer I/O port from which it was requested.

Introduction 16-5

Status Response Syntax
All status responses start with the letters PCL followed by a Carriage Return control code (decimal 13; <CR>) and a Line Feed control code (decimal 10; <LF>). In addition, each remaining line of the response is terminated by a Carriage Return and Line Feed control code. Finally, status responses are terminated by a Form Feed control code (decimal 12; <FF>). The basic syntax for the status response is shown below. PCL<CR><LF> INFO TITLE<CR><LF> KEYWORDn=DATAn<CR><LF> KEYWORDn=DATAn<CR><LF> M <FF> TITLE, KEYWORDn, and DATAn are strings that vary depending on the particular status readback command being executed. Each status readback response has one or more keyword lines associated with it. A slight variation of this is the Echo command response. This response is shown below. PCL<CR><LF> ECHO ValueField<CR><LF> <FF> ValueField is the decimal number taken from the Echo command value field. Note Keywords may be added for future printers that are not documented here. Applications that use status readback should be designed to ignore lines with keywords they do not recognize. Two example status responses are shown below.
PCL<CR><LF> INFO MEMORY<CR><LF> TOTAL=100000<CR><LF> LARGEST=25000<CR><LF> <FF>

In the example listings, <CR>, <LF>, and <FF> identify the Carriage Return (decimal 13), Line Feed (decimal 10), and Form Feed (decimal 12) control codes. The <Esc> following the SELECT= keyword is a five character representation (the printable characters: <, E, s, c, and >) and does not identify an escape control code (decimal 27). The examples in the remainder of this chapter do not show the status response line termination (<CR><LF>) control codes, or the termination (<FF>) control code. Example responses in this chapter for SYMBOLSETS= do not list the complete list of internal available symbol sets, only a partial list: 0D,0I,0N,0S,0U,1E,1F,1G,. The internal symbol sets are printer dependent and may vary from printer to printer. Refer to the PCL 5 Comparison Guide for printer specific information.
