Enable PJL Device Access Commands for Samsung ML-4050N Printer

WHITE PAPER

SAP COMPATIBILITY FOR THE SAMSUNG ML-4050N PRINTER

Test Methodology

The lab logged an SAP Client on to a session with the SAP Server. They created a Samsung PRI file device definition with the host spool access method set to emulate printing from the following:

•Front-end computer

•Device pool

•Operating system call.

Observation

There were no issues found during the testing of these Spool Access methods. The print jobs sent using different spool access methods worked as expected with the Samsung ML-4050N printer.

Loading

Description

Printing large print jobs can cause problems for some printers. The lab tested the Samsung ML- 4050N printer behavior during high loads, and verified how it responds in an SAP environment.

Test Methodology

The lab logged an SAP Client on to a session with the SAP Server. They sent the following loads to the printer through the SAP environment:

•100 copies of an SAP report

•Over 100 copies of an SAP report

•A print job that lasted for one hour.

Observation

The Samsung ML-4050N printer printed on average 40 letter pages in 1 minute as per specifications. The prints did not show any smudging or fuzzy edges. The printer printed the SAP reports for one hour without any interruption and the quality of the printing was good.

Using PJL Commands

Description

PJL commands are printer settings that you can modified as needed in the Device Type file. When you make changes to these PJL commands, the changes will display in the printer output. You can enable or disable the PJL commands that a device file supports for configuring different settings.

Test Methodology

The lab logged an SAP Client on to a session with the SAP Server. They created a Device Type and Output Device for Samsung in the SAP Client.

They selected the ZMINDEF format provided by Samsung, and from the Printer Initialization window, they changed the Resolution and the Duplex printing PJL commands and saved them. They printed the SAP report using the Samsung Output Device created and verified for the testing of the PJL command settings.

Observation

The Samsung ML-4050N printer did not accept the PLJ commands for changing the Resolution or the number of copies. This printer does not accept PJL commands to set the printer settings, when connected to an SAP Client machine through USB or TCP/IP.
