4 Device dependent 0 to 2 - Command is ignored for out of range values
Determines whether black optimization is performed to make process black (composite blackcomposed of color inks) appear more black. When composite black is constructed by setting all the bits in the CMY color planes, the resulting color may not be isotonic. Gray balancing removes some dots to neutralize the hue shift. Esc E resets Gray Balance to the device-dependent default. The default for the HP DeskJet 550C is 2 (disable gray balancing). The defaults for the HP DeskJet 540 and HP DeskJet 600 printers are Print Mode and Media Type dependent - as shown in the following table. Other HP DeskJet printers do not require gray balancing, as the gray balance function is built into the Media Type/Print Quality commands. The Gray Balance command is considered obsolete for those printers. Gray Balance Default Modes HP DeskJet 540 Print Mode

Dry Timer

TABLE 10.

Dry Timer - Esc

&b#T

0 1.1200 Default Range
Dry Timer is off Dry timer is on - time set for specified number of seconds
to 1200 - Command is ignored for out of range values
Sets a minimum dry time between pages to ensure that a previous page dries before the next page is dropped on top of it. The time required for ink to dry depends on media, print modes, and environment (temperature and humidity). For example, transparencies may need over 10 minutes in an unheated, damp environment. Esc E resets the dry timer to the default value of 0. The Dry Timer function has been incorporated into the Media Type/Print Quality command combination. The parameters specified for those commands determine the Dry Timer setting. Although some HP DeskJet 600/800/900 & HP 2000 Series printers will respond to this command, the command is considered obsolete. Dependence on the command should be removed from your application. The HP DeskJet 600/800/900 & HP 2000 Series printers use the following values as Dry Timer defaults when Media Type and Print Quality commands are used: Dry Timer Defaults EconoFast Mode Normal Mode Black

Prints any unprinted pages. Ejects the current page if printable data has been received (FF-CR). Sets text length, top margin, left margin, and right margin to user defaults. Moves CAP to the left edge of the logical page at the top of form.
The printer may select a different page size for the same line count, since lines are defined by the current VMI. This command is ignored if VMI is 0. For comparison purposes, the following table lists the page length line values associated with some standard paper sizes. To calculate the number of lines per page, multiply lines per inch (lpi) times the length of the physical page. For example, US Letter size paper is 11 inches; therefore, 6 x 11 = 66. Page Length Line Values
Letter Legal A4 Executive
HP DeskJet maximum page length is 14 inches for the HP DeskJet 600/800/900 & HP 2000 Series printers. This command must be sent at the beginning of a page prior to any printable data; otherwise, when the command is sent, the current page is closed and printed. Page Size

Designates the size of the media to be used. This command performs the following actions:
Prints any unprinted pages. Ejects the current page if printable data has been received (FF-CR). Sets text length, top margin, left margin, and right margin to user defaults. Moves CAP to the left edge of the logical page at the top margin. Disables the automatic macro overlay.
Since the logical page is defined to extend from the top and bottom edges of the physical page, this command also sets logical page length.

Font Pitch (Primary) -
Esc ( s # H Font Pitch (Secondary) - Esc ) s # H
Inter character spacing for current font is set
10 cpi > 0.0 - valid to 2 decimal places - Command is ignored for out of range values
Designates the horizontal spacing of a fixed-space or dual-fixed space (bitmap or scalable) font in characters per inch (cpi).
If the exact pitch is unavailable, the next larger pitch is selected. If a larger pitch is unavailable, the closest smaller pitch is selected. Pitch is ignored when selecting proportional fonts, but saved in the font select table and available when a fixed space font is selected. For fixed space bitmap fonts, both pitch and height are used for font selection. For fixed space scalable fonts, only pitch is used. For proportional scalable fonts, only height is used. For dualfixed space fonts, only the pitch is used. For scalable fonts, pitch is converted to a corresponding point size (height), which is scaled by the printer. Effective pitch ranges are thus limited by height constraints. 10.11.5 Font Height

TABLE 39.

Font Height (Primary) -
Esc ( s # V Font Height (Secondary) - Esc ) s # V
Height for current font is set
12 points > 0.0 - valid to 2 decimal places - Command is ignored for out of range values.
Specifies font height in points (1/72 inch).
If the requested height is unavailable, the closest heights are chosen for the next selection criteria. The closest value is in terms of absolute difference: e.g., if 6, 8, and 12 point fonts are available and 10 is requested, both 8 and 12 point fonts are considered. Fractional values may be specified when requesting height. All bitmap fonts within 0.25 points of the requested height are considered. If a 12 point font is requested, fonts between 11.75 and 12.25 are considered. Or, to put it another way, if 6, 8, and 11.75 point fonts are available and 10 is requested, both the 8 and 11.75 fonts are considered. Height is ignored when selecting a fixed space scalable font; but the value is saved in the font select table and available when a proportional font is selected. If no font within.25 points is available, HP DeskJet selects the next smaller height. If no smaller height is available, the next larger height is selected.

group of bytes sent by one command is called a block. A character definition consists of a first block and zero or more continuation blocks. An unsupported or invalid character definition is ignored and discarded. An out-of-memory condition during character download deletes the entire font. Reserved fields should be set to 0. 10.12.5 Font Control

0 to 5 - Command is ignored for other values, or if no font has the specified ID
Manipulates fonts and characters designated by Font ID and Character Code. If the primary or secondary font is deleted, a new primary or secondary font is automatically selected from the remaining fonts.

Raster Graphics

The following HP PCL commands apply to the printing of raster graphic images on HP DeskJet 600/800/900 & HP 2000 Series printers.

10.13.1

Raster Mode The Start Raster (Esc * r # A) command begins a restricted state called raster mode. Raster mode locks out commands that would affect rendering of the graphics image. These commands remain locked out until End Raster (Esc * r C).

10.13.2

Commands Locked Out of Raster Mode The following raster commands are ignored in raster mode. They should be used to define a graphic images parameters before entering graphics mode. Configure Raster Data Simple Color Source Raster Width Start Raster Esc * g # W Esc r # U Esc r # S Esc r # A

10.13.3

Commands Allowed in Raster Mode The following commands may be used in raster mode without implicitly ending raster mode. Compression Method Seed Row Source Transfer Raster by Row/Block Transfer Raster by Plane Y Offset Esc b # M Esc b # S Esc * b # W Esc b # V Esc b # Y

10.13.4

Start Raster

TABLE 48.

Start Raster -

Esc * r # A

Start graphics at logical page left boundary (current vertical position) Start graphics at CAP (current vertical and horizontal position)

1 Default Range

to 1 - Out of range values default to 0
Starts raster mode and specifies the starting position of the raster image. This command sets the left raster margin. A value of 0 starts the upper left corner of the picture at the current vertical position on the left edge of the logical page. A value of 1 starts the upper left corner of the picture at CAP (the current vertical and horizontal position). Start Raster locks out the commands listed above and clears the seed row. 10.13.5 End Raster

10.14.1

Transfer Raster by Plane

TABLE 53.

Transfer Raster by Plane - Esc

* b # V [data]

Specified number of bytes of graphics data for a single plane of data is set to the printer. The row pointer is not incremented.
n/a 0 to 32767 - Command is ignored for out of range values
Sends a plane of data to the printer and advances to the next plane, but not to the next row. The number of planes per row is specified by the Simple Color (Esc * r # U) command (also known as Set Planes per Row). The first plane sent represents the least significant bit in the pixel. Since Transfer Raster by Plane (Esc * b # V) does not advance the row, it cannot be used for the last plane or for single-plane rows. Only Transfer Raster by Row (Esc * b # W) can advance the row. The amount of data sent varies from plane to plane and is independent of raster width. Planes whose data specifies a row shorter than the raster width are zero-filled. Empty planes can be sent by Esc * b 0 V.

10.14.2

Transfer Raster by Row/Block

TABLE 54.

Transfer Raster by Row or Block - Esc

* b # W [data]

Following specified number of data bytes sent to the printer as K data
Transfers the number of bytes specified in the value field to the printer in a row by row or block format, depending on the current compression method (Esc * b # M), then moves CAP to the next row. This command is used in single-color and multi-color printers where data is encoded by row rather than by pixel. Because this command advances the row, it is also used for single-plane rows or the last plane in a multi-plane row. CAP is updated for each row in both row or block formats. For row formats, CAP is reset to the left graphics margin. For block formats, CAP is reset to the X coordinate of the block; and the Y coordinate is incremented. The amount of data sent by this command can vary from row to row. If the picture width allows more data than is sent, the undefined area is zero-filled. Undefined planes in a multi-plane row are zero-filled. Black and white devices interpret zeros as white; color devices interpret zero according to the current palette. The plane pointer in a multi-plane row is reset to 1 after the data is transferred. The data field is interpreted according to the current compression method (Esc * b # M).

Raster Compression

Since raster images take a large amount of memory and processing time, raster data should be reduced as much as possible. White-space data transfer can be reduced by sending empty rows and planes (Esc * b 0 W, Esc * b 0 V), or by offsetting the left graphic margin (Esc * r 1 A) or the vertical starting point (Esc * b # Y). The Compression Method (Esc * b # M) command provides several other ways of compressing data.

EXAMPLES OF METHODS 0 - 2: The following examples show how methods 0 - 2 can be used to send the raster row below:
Byte Number #1 #2 #3 #4 #5 #6 #7
01010101. 01010101. 01010101. 01010101. 01000001. 01010100. 01010100 U U U U A T T
Compression method 0 - Unencoded Esc*r1 A Esc*b0m7WUUUUATT Esc*rC
Compression method 1 - Run-length encoding Esc*r1 A Esc*b1 m6W(3)U(0)A(1)T Esc*rC Compression method 2 - TIFF encoding Esc*r1 A Esc*b2m6W(-3)U(0)A(-1)T -orEsc*b2m6W(-3)U(2)ATT Esc*rC Parentheses in the above escape sequences are for readability only.
Method 3 - Delta Row Encoding This method replaces only bytes in the current row that are different from the preceding row (seed row). Unreplaced bytes are replicated from the seed row. The current row then becomes the seed row. A delta compression string consists of a command byte and the replacement (delta) bytes: [(Command byte)(1 to 8 replacement bytes)] The command byte has two parts: the number of consecutive replacement bytes that follow, and the left offset from the current byte position. 4 0
Replacement count (1 - 8)
Left offset from the current byte (O - 30)
Three bits of the command byte contain the replacement count: the number of consecutive replacement bytes that follow (000 = 1, 111 = 8). Five bits contain the offset from the current byte to the next replacement byte. The current byte follows the last replacement byte or, at the beginning of a row, the left graphics margin. An offset of 0 is the current byte; an offset of I is the byte following the current byte. For example, assume the current byte is the first byte in the row. An offset of 7 skips bytes 0 through 6, and a replacement count of 5 replaces bytes 7 through 11. The new current byte is 12. A second offset of 3 skips bytes 12, 13, and 14; byte 15 is the next byte to be replaced.
The values of the offset have the following definitions: 0 to 30: 31: The offset is 0 to 30. The offset is 31 or greater. If the offset is 31, an additional offset byte follows the command byte. The offset in the command byte is added to the offset byte. If the off- set byte is 0, the offset is 31; if the offset byte is 255, additional offset bytes follow. The last offset byte will have a value less than 255. All the offset bytes are added to the offset in the command byte to get the offset value. For example, if there are 2 offset bytes, and the last byte contains 175, the total offset would be: 31 + 255 + 175 = 461.
If more than eight delta bytes are needed, additional command byte/delta bytes are added: [(Command Byte)(1-8 Delta Bytes)][(Command Byte)(1-8 Delta Bytes)]. The seed row is zeroed when raster mode is entered. Every raster transfer affects the seed row, regardless of the compression method. For example, an Esc * b 0 W while in compression method 0 zeros the seed row. This allows method 3 to be combined with other methods in order to achieve better compression performance. A vertical offset also affects the seed row: the Y Offset (Esc * b # Y) command skips rows, leaving them blank, and zeros the seed row. Method 3 operates on each plane independently, and a separate seed row is maintained for each graphic plane. However, a Y Offset affects all planes and seed rows simultaneously. The examples below show how method 3 affects Raster Transfer and Y Offset commands: Esc b 0 W Esc b 1 Y Esc b 0 Y Repeat the previous row. The seed row is unchanged Move down one raster row. Zero the seed row. Move down zero raster rows. Zero the seed row

7 Control Bit = 1

Seed Row Source Esc * b # S Specifies the plane of the seed row for multi-plane graphics in compression methods 3 and 9. Value (#) Default = 0 Range = 0 to number of currently active planes. For example, if the printer is in 3-plane mode and Esc * b 0 S was sent, then: = = 0 - Use the corresponding plane of the previous row. > 0 - Number of previous seed planes before the current plane
4 The Cyan plane would use the Cyan plane from the previous row

as a seed plane.

4 The Magenta plane would use the Magenta plane from the previous

row as a seed plane.

4 The Yellow plane would use the Yellow plane from the previous
row as a seed plane. If the printer is in 3-plane CMY mode and Esc * b 1 S is sent, then:
4 The Cyan plane would use the Yellow plane from the previous row as

a seed plane.

4 The Magenta plane would use the Cyan plane from the current row
4 The Yellow plane would use the Magenta plane from the current row

The Simple Color (Esc * r # U) command, sometimes referred to as Set Planes Per Row, allows color selection from a fixed palette. CMY or RGB raster data must be transferred by plane (Esc * b # V) as well as by row (Esc * b # W). The pixel encoding mode is indexed planar.Creates a fixed-size palette whose color specification cannot be modified. The HP DeskJet 600 printer, which is a single-pen device, maps a value parameter of -4 to 3-plane CMY, converting K data to composite black. The absolute value of the value field indicates the number of planes per row of raster data to be sent. The number of entries in the new palette is 2n, with index values 0 to 2n -1. For example a 4-plane palette has 16 entries, with index numbers 0 to 15. A value field of 1 creates a 2-entry black and white default HP LaserJet palette. A value field of 3 creates an 8-entry Device RGB palette (compatible with a HP PCL Imaging Mode palette. A value field of -3 creates an 8-entry palette in Device CMY color space. A value field of -4 supports 4-plane Device KCMY color. Plane 1 is the black pen, and planes 2, 3, and 4 respectively are the CMY planes. The four Simple Color palettes are shown below. The ordering for color data planes when the RGB palette is selected is RGB. The first Transfer By Plane command will send Red Data to the printer, the second will send Green Data, and the Blue Data is sent with a Transfer By Row command, which increments the

12.0.5

Orientation (UBYTE) Bitmap fonts only. Specifies the orientation of the character. Character orientation must match the orientation in the font descriptor, as follows: Value Orientation Portrait Landscape Reverse-portrait Reverse-landscape
The character is discarded if the orientation is not supported or is different from the font orientation. 12.0.6 Left Offset (SINT) Bitmap fonts only. Specifies the distance in dots from the reference point to the left side of the character pattern on the physical page coordinate system (i.e. this value is orientation dependent). The left and top offsets locate the character reference point about CAP. HP DeskJet 600 and 85X Series printers recognize a range of -16384 to 16384. 12.0.7 Top Offset (SINT) Bitmap fonts only. Specifies the distance in dots from the reference point to the top of the character pattern on the physical page coordinate system (i.e. this value is orientation dependent). The left and top offsets locate the character reference point about CAP. HP DeskJet 600 and 85X Series printers recognize a range of -16384 to 16384. 12.0.8 Character Width (UINT) Bitmap fonts only. Specifies the width of the character in dots on the physical coordinate system (i.e. this value is orientation dependent). Generally, this width is from the farthest left black dot to the farthest right black dot. HP DeskJet 600 and 85X Series printers recognize a range of 1 to 16384. 12.0.9 Character Height (UINT) Bitmap fonts only. Specifies the height of the character in dots on the physical coordinate system (i.e. this value is orientation dependent). HP DeskJet 600 and 85X Series printers recognize a range of 1 to 16384.

12.0.10

Delta X (SINT) Bitmap fonts only. Specifies the number of quarter-dot units (radix dots) by which the horizontal position within the HP PCL logical page coordinate system is incremented after printing the character. If the value field is negative, the value is set to 0. This value is used by the printer only when the font is proportionally spaced.

Character Data The character data is in the format specified by the class field.

Banner Printing

The following information concerns the printing of continuous forms (banners, z-fold media) on the HP DeskJet 680 and 690 Series printers. This is the only information made available by the VCD R&D lab. There are no new HP PCL commands for banner printing. The only HP PCL command that has actually been modified in association with printing on continuous media is the command. Only media sizes (as selected with the Media Size command) US Letter and ISO/JIS A4 can be used for continuous form printing.

13.0.4

Moving to a New Logical Page Since raster graphics moves are clipped to the current logical page, it is necessary to explicitly move to a new page once the current page is filled. As shown in the HP PCL example on the following page, this may be accomplished by sending a form feed (followed by the appropriate cursor positioning). Raster graphics advances never move to the next page, any excess rasters (raster data that would exceed the logical page boundary) will be discarded. If a raster block spans a page boundary, it must be sent as multiple blocks, along with the appropriate cursor positioning to align on the physical media. For text printing on continuous media, line feeds or form feeds may be used to advance to the next logical page.

13.0.5

Unloading Continuous Media When the printer has completed a continuous-media print job, it will advance the paper to the end of the page after the current page. If media remains in the mechanism, the top LED will flash. Pressing the Resume button will advance one page. Media must be removed and reinserted between each banner print job.

13.0.6

Power-On with Continuous Media The firmware will remember what media type is loaded. If powered down with continuous media loaded, the firmware will power on with the top LED flashing (as described above) allowing the user to unload the continuous media if cutsheet media is desired for the next print job.

13.0.7

Power-Off with Continuous Media If the Power key is pressed while in the middle of a banner page, the media will first be advanced to the next top of form before turning the printer off. Any unprinted data will be lost.

13.0.8

Printing Cutsheet with Z-Fold Media Attempting to print cutsheet media while z-fold media is loaded and there exists a bidirectional I/O connection between the host and printer, will halt the printer in an error state. Power cycling will clear the error. Without a bidirectional I/O connection, the printer will format and print the cutsheet job on the z-fold media.

HP PCL Code Samples

The following pages contain PCL code samples that are intended to address some of the most commonly asked support questions. Key among these questions are coding general page formatting, 4-plane color graphics, and using Configure Raster Data (CRD).
Page Formatting Program Example
The following example is old, but covers the essential page formatting commands. While there is no one best way to write a page formatting program, you can use this example as a starting point. When performed in the order given, the set of commands prints the output shown in the figure at the end of the example. The example assumes the following formatting objectives:
Select US Letter size paper Select portrait page orientation Set 3/4 in. top, left, and right margins Set 11/4 in. bottom margin Establish a header centered approximately in the middle of the top margin Establish a footer 5/8 inch from the bottom of the paper Set line spacing at 8 lpi Use Letter Gothic and CG Times typefaces No assumption is made as to the status of the configuration switches.
