If your printer has multiple paper trays, you can control which one is used from the SAP System.

Pages in SAP

Print Controls are used to control tray selection:

Device definition
If the SAP device definition for your printer does not contain the print controls described above, do the following:
Background: The SAP spool system cannot use this information to switch paper trays according to the output. But it does use this information to detect potential incompatibilities between the output format and the available paper types. It then chooses the best available format for printing at this device.

To test tray selection, use the standard text
Device definition (with list printer drivers)
If your output device uses one of the following device types:
go to the Output attribute tab page in the device definition. Under Paper tray, specify the default tray to use for printing lists. For Tray info, enter the page formats available at the printer. If Tray info is not available, the system prints using an intersection of the DINA4 and LETTER page formats.
If you want to use several of your printer’s trays, you must create an output device for each paper tray, for example,
P99_TRAY1 , P99_TRAY2, and so on.
If your printer does not use any of the specified device types, you must add a command to activate a particular paper tray to a format. For more information, see
