SCRIPTSERVER® SUPPORT FOR TRAY SWITCHING

Revised: 13-Aug-2002

Contents | Index | About the Icons

Some multiple-tray PostScript printers provide the ability to automatically switch the paper source between input trays as they become empty. The ScriptServer printer status report shows the setting for this capability. If the printer does not support tray switching, the value will be printed as "-unimplemented-". To generate a status report, send the PRINTER_STATUS job to the printer.

ScriptServer for OpenVMS

execute the following command:
$ PRINT/QUEUE=queue-name SCRIPTSERVER:PRINTER_STATUS.PS

ScriptServer PAN Printing System

Use the web interface to submit the file to the queue.

Tray switching can usually be permanently enabled (or disabled) by changing the value on the printer's front panel control menu, or by sending the following PostScript code to the printer:

%!PS-Adobe
0 serverdict 
/exitserver get exec
statusdict begin
true setdefaulttrayswitch
end

Note: To disable the tray switching command permanently, replace the "true" value in the preceding code with "false".

With ScriptServer for OpenVMS, tray switching is disabled on some printers as a result of the ScriptServer symbiont issuing tray selection commands. When this occurs, ScriptServer's tray selection can be disabled using the logical name:

SSV$device_name_TRAY_tray-command

As an example, suppose this problem exists for the ScriptServer queue on device LTA100: and that the paper in use is LETTER. To disable the tray selection command issued by ScriptServer, the logicalname to define is:

$ DEFINE/SYSTEM SSV$LTA100_TRAY_LETTERTRAY " "
