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.
