Faster on-demand printing Instant-on Technology enables your HP LaserJet P4015n to print up to 23 pages from powersave mode before the Samsung ML-4551N can even finish warming up. This advantage is especially noteworthy when you consider that most printers are usually in sleep mode when a user submits a job for printing, according to research conducted by InfoTrends. Less complexity Your HP LaserJet P4015n print cartridges dont require shaking. Samsung ML-4551N toner cartridges do. And unlike the Samsung cartridges, your HP LaserJet print cartridges have a shutter to protect the imaging drum whenever you access the paper path. Fewer interventions Your HP LaserJet P4015ns maximum input capacity is 71% greater than the Samsung ML-4551Ns (3,600 sheets vs. 2,100 sheets, respectively), so you dont have to stock paper as frequently. Likewise, you can replace print cartridges less frequently because your HP LaserJet high-capacity print cartridges can yield up to 24,000 pages in default mode vs. 20,000 pages for Samsung high-capacity cartridges. Energy efficient The advanced, fast-heating ceramic element within your HP LaserJet P4015ns Instant-on Fuser consumes 37% less energy than the conventional fuser Samsung builds into the ML-4551N (an estimated 216 kilowatt hours per year vs. 343 kWh, respectively). Greater security options The HP LaserJet P4015n supports 802.1x, SNMP v.3 and IP sec three security protocols that Samsung does not support. HP also has a 10 key pad for simplified PIN printing, while Samsung offers no 10-key pad and requires purchase of an optional hard disk for PIN printing through the control panel.

Test Results

The lab tested the Samsung ML-4551N printer in a Citrix environment using the Citrix printing features. They tested both the PCL and PS drivers using Windows XP.

Test Scenarios

The tests included several test scenarios designed to verify the compatibility of the Samsung ML-4551N with Citrix. The test scenarios include the following: Auto Creation of Client Printers Citrix Universal Printer Driver Client Driver Compatibility Using Session Printers Replicating Printer Drivers Mapping Client Printer Drivers Verifying Client Driver Properties Using a Network Print Server Shadowing Client Printers Using Driver Features Using the Interface Using Printer Policies Printing from a Server Using Driver Policies Installing Printer Drivers.
Observation The Samsung ML-4551N printer was successfully auto-created, and there were no printing issues using the PCL6 and PS drivers.
Citrix Universal Printer Driver
Description Citrix uses the Citrix Universal Printer Driver to autocreate printers on the server when the native printer driver is not available from the client. The Citrix Universal Printer Driver supports the following printer control languages: PostScript (PS) PCL5C PCL4
Test Methodology The lab connected the Samsung ML-4551N printer to a client using a USB cable and they installed the printer driver on the client. They made an ICA connection from the client to the server. They did not install the Samsung ML-4551N printer driver on the server. Observation Citrix successfully used the Citrix Universal Printer Driver to auto-create the driver on the server. The lab printed to the Samsung ML-4551N printer from the server using this driver and experienced no issues.
Auto Creation of Client Printers
Description The Auto Creation feature displays the client machine printers on the server during an ICA connection. The server users can print from these auto-created client printers. When a user logs on to a server farm, Citric creates their configured printers in the session automatically, without requiring an installation of the printer drivers or printers located on the client system. Test Methodology The lab connected the Samsung ML-4551N printer to a client using a USB cable and they installed the printer drivers on the client. They made an ICA connection from the client to the server. All of the client printers in were autocreated on the server. The lab printed from the server using the auto-created client printers.
Client Driver Compatibility
Description Client Driver Compatibility in Citrix provides an option you can use to prevent Auto-Create from creating drivers on the server from the client printers. This option allows you to prevent a problematic driver from causing a fatal system error on the server. Test Methodology The lab connected the Samsung ML-4551N printer to a client using a USB cable and they installed the printer driver on the client. They made an ICA connection from the client to the server. From the Presentation Console of the server, the lab disabled the Auto-Create feature for the Samsung ML-4551N printer driver by using the Client Driver Compatibility feature. Observation When the lab connected the client to the server using an ICA connection, the Client Driver Compatibility feature prevented Auto-Create from creating the Samsung ML-4551N printer driver on the server. The Samsung ML-4551N printer exhibited no issues during the testing of this feature.

They enabled the Samsung ML-4551N printer as a session printer for the client by using the Session Printer Policy from the Presentation console of the Server. The lab made an ICA connection from the client to the server. Observation The Citrix client recognized the Samsung ML4551N printer as a Session Printer during the ICA connection. The lab successfully printed from the Samsung ML-4551N Session Printer.
Replicating Printer Drivers
Description Driver Replication is a Citrix Server feature that allows printer drivers installed on one server to replicate to another server in the same server farm. This feature reduces the overhead caused by installing the printer on each Server separately. This feature saves time and it ensures that newly installed drivers are available from all of the servers. Replicating printer drivers in the server farm ensures that the ICA client users can print to any of the client and the network printers located on the server farm. Test Methodology The lab joined two servers (Server1 and Server2) to create a server farm. They installed the Samsung ML-4551N printer driver on Server1 and not on Server2. Then they replicated the driver from Server1 to Server2. Finally, they established an ICA connection to Server2 from the client. Observation The lab used Auto Create to create the client printers on Server2 using the replicated Samsung ML-4551N printer driver. They successfully printed through the auto-created client printer. The lab did not encounter any issues with the Samsung ML4551N printer on any of the operating system platforms tested.

Using Session Printers

Description Citrix Presentation Server defines policy-based session printers as printers attached locally to a Server running Citrix Presentation Server or as shared printers imported from a Network Print Server. When Citrix applies the Session Printer Policy to a user, it creates the configured printers for that user automatically for any log on session with a Server farm, without requiring an installation of the printer drivers or the presence of a printer on the client system. Test Methodology The lab connected the Samsung ML-4551N printer to a client using a USB cable or by creating a TCP/IP port.

Mapping Client Printer Drivers
Description The Citrix Presentation Server Driver Mapping feature allows users to substitute specific Windows printer drivers for client printers. Each client provides information about the printers during logon, including the printer model name. During client printer auto-creation, the selected Windowsserver printer driver names correspond to the printer model names provided by the client. The auto creation process then employs the identified, available printer drivers to construct redirected client print queues. In some cases, the printer model names provided by the client do not correspond directly to the printer driver names on the Windows-server. When this happens, auto creation will fail, unless the administrator designates a surrogate driver. Administrators can also use the Citrix Presentation Server Driver Mapping feature to force families of compatible printers to use a single reliable driver. Test Methodology The lab connected the Samsung ML-4551N printer to a client by using a USB cable. They also installed the driver for this printer on the server and on a client with a different name than used on the server. The lab used the Presentation console to map the clients printer driver to the servers printer driver. Then they made an ICA connection from the client to sever. Observation Citrix auto-created the client printers on the server during the ICA connection and mapped the clients printer driver to the driver present on the server. The lab successfully printed through this client auto-created printer using the mapped driver.
You perform these settings locally on the client machine. These settings include orientation, paper size, pages per sheet etc. Citrix displays these printer driver properties in the settings for the autocreated client printer. Test Methodology The lab connected the Samsung ML-4551N printer to the client by using a USB cable. They installed the printer driver on the server and on the client. Then they verified the printer driver properties of the auto-created printer against the printer driver properties on the client machine. Observation The lab confirmed that the printer driver settings of the auto-created client printers are the same as the settings on the client machine. The changes they made to the printer driver properties on the client machine were present on the auto-created client printers when they established an ICA connection with the server.

Using a Network Print Server
Description Citrix Network Print Servers are servers to which you attach shared printers. You import these shared printers to the Citrix Presentation Server and assign them to users through policies. Test Methodology The lab connected the Samsung ML-4551N printer to the Citrix Print Server using a USB connection or a TCP/IP connection. They verified the availability of shared printers. The lab then imported the shared printer to the server and configured it for a specific user through the session policy. That user then connected to the server by using an ICA connection. Observations
Verifying Client Driver Properties
Description In Citrix, driver properties refer to the printer configuration settings you make to the client system. The lab confirmed that the Print Server was available for printing in the tested session. They successfully printed to the Samsung ML-4551N printer by using that session.
Shadowing Client Printers
Description Citrix shadowing is a feature that allows users to view and control other users sessions remotely. You can use session shadowing to monitor and interact with users sessions. When you shadow a user, you can view whatever appears on the users session display. Shadowing is a useful tool for user collaboration, training, troubleshooting, and monitoring by supervisors, help desk personnel, and teachers. You can use the Citrix Shadow Taskbar to shadow sessions and to switch among multiple shadowed sessions. Test Methodology The lab selected the shadowing option in Citrix Server, and then they selected a user desktop to shadow. They verified the actions performed on client side against those performed on the user side. The lab rejected shadowing of the desktop and verified whether this step blocked shadowing from occurring. The lab connected the Samsung ML-4551N printer to the client by using a USB connection or TCP/IP connection. They selected a users desktop to shadow for the test. Then the lab tested the print drivers while shadowing the user. Observation The lab successfully shadowed the user and observed their actions performed on the server side from the client side. Then they successfully printed to the Samsung ML-4551N printer using the PCL 6 and PS drivers over the shadow session. The lab encountered no issues on any of the tested Windows operating systems.

Using Driver Features

Description A printer driver contains the printer instructions you can configure to control a printers features. These features allow you to output your print jobs by using different printing formats. Printer features can include watermarks, overlays, etc. You should get the same results using these printer features from an auto-created client driver, as you would get from a local client printer driver. Test Methodology The lab connected the Samsung ML-4551N printer to the Citrix Presentation Server machine using a USB connection or using a TCP/IP connection. They installed the printer driver on the server and on the client machine. The lab created a Microsoft Word document named Data.doc on the server. The lab established an ICA connection from the client to the server using MS Word from the server. They opened and printed the Data.doc file from the Server to test the watermark, overlay, and n-up printing features of the driver during the ICA session. Observation The lab successfully printed to the Samsung ML4551N printer using the watermark, overlay, and nup driver features without encountering any issues on any of the Windows operating systems tested.
Using the Printer Driver Interface
Description The Printer Driver User Interface is the interactive visual representation of the printer features and their settings presented in a format that allows a user to configure or arrange the printer settings to accommodate their printing requirements. A Printer Driver User Interface provides the following: Control over the printer input, allowing the user to manipulate the system. Control over the printer output, allowing the system to produce the desired user-configured effects.

Using Printer Policies

Description You use Citrix Presentation Server Printer Policies created in the Presentation Server Console to configure printer management. Presentation Server Printer Policies provide a mechanism to define a collection of system settings that can be associated with a broader range of criteria than just users, groups, and computers. You can use policies to establish farm-wide defaults for server settings. You assign Presentation Server Printer Policies through filters that apply rules defined by using any combination of the following criteria: Access Control Client IP address Client Name Servers Users.
The goal of any user interface is to provide easy navigation, accessibility, and a logical flow of the user interaction. It must provide an environment that any user can understand and that they can use to create their expected output. Test Methodology The lab installed the Samsung ML-4551N PCL 6 driver on the Citrix Presentation Server machine and on the Citrix Client. They established an ICA connection from the client to the server by using MS Word from the Server side. The lab connected the printer to the server. They tested the Samsung Printer Driver User Interface print window for navigability, accessibility, and functionality. The lab accessed all of the UI tabs such as Page Order, Page Orientation, etc. Observation The lab found all of the Samsung Printer Driver User Interface tabs to be functional, navigable, and user friendly. They did not encounter any issues while testing the Samsung ML-4551N printer on any of the Windows Operating systems tested.

Test Methodology The lab connected the Samsung ML-4551N printer to the Citrix Presentation Client machine by using a USB connection or by using a TCP/IP connection. They installed the printer driver on the Client. Then from the Citrix Presentation Console the lab enabled the server Auto Create all Client Printers policy and applied it to the following: A range of IP addresses One particular IP address A specific client name One particular user
The lab tested the auto creation of client printers after they applied each of these policies. Observation Citrix successfully auto-created all of the client printers to which the policies were applied.

Printing from a Server

Description Printing from a server is the process of using any of the Citrix access options to print from a locally connected server printer and from a network printer. Test Methodology The lab connected the Samsung ML-4551N printer locally to the Citrix Presentation Server machine by using a USB connection or a TCP/IP connection. They installed the printer drivers on the Server. Then the lab established an ICA connection from the client to server by using MS Word from the Server side. The lab verified the printing ability of the printer drivers during the ICA session by firing a test print using the Server local printer drivers in the ICA session. The lab connected the Samsung ML-4551N printer to the Host-A machine and shared the printer in the Citrix Presentation Server machine network. They installed the printer driver on the server machine by using the Import Network Print Server feature in the Citrix Presentation Console. The lab enabled the Session Printer Policy applied it to the client machine. They established a new ICA connection between the client and the server by using MS Word from the server side. Then the lab verified the Printers and Faxes window for the Network Print Server installed on the server side of the ICA session and fired a test print to verify the functionality of the installed network printer. Observation The lab successfully installed the printer drivers on the server and printed through the server printer driver. Then they successfully used the server network printer to print from the server side. The lab did not encounter any issues testing this feature on any of the Windows Operating Systems.

Using Driver Policies

Description Citrix Driver Policies provide a mechanism you can use to define a collection of system settings for a broader range of criteria than just users, groups, and computers. Driver Policies basically, deal with the native printer drivers and the universal printer drivers. Test Methodology The lab connected the Samsung ML-4551N printer to the Citrix Presentation Client machine by using a USB connection or a TCP/IP connection. Then they installed the printer driver on the client and the server machines. The lab enabled Native Printer Drivers and Universal Printer Drivers policies from the Citrix Presentation Console of the Server. Observation The lab observed that Citrix successfully autocreated the client printer drivers by only using the native printer drivers when the Native Printer Drivers policy was enabled. They did not encounter any issues testing this feature on any of the Windows Operating Systems.
Installing Printer Drivers
Description Proper installation and removal of the Samsung ML-4551N printer drivers on the Citrix Presentation Server 4.5 and on the Citrix Presentation Client machines is essential for adding and removing system printers. Test Methodology The lab connected the Samsung ML-4551N printer to the Citrix Presentation Server 4.5 machine locally by using a USB or a TCP/IP connection. Then they installed and removed the Samsung ML-4551N series printer driver from Citrix Presentation Server 4.5 machine. The lab connected the Samsung ML-4551N printer to the Citrix Presentation Client machine locally by using a USB or a TCP/IP connection. Then they installed and removed the Samsung ML4551N series printer driver from Citrix Presentation Client machine. Observation The lab did not encounter any issues installing or removing the Samsung ML-4551N series printer driver for either the server, or the client with a printer connected to the server or the client locally using any of the Windows Operating Systems.
