A DESCRIPTION OF THE REQUEST :
When trying to use javax.print.DocPrintJob to print a PostScript document on a printer that has multiple output trays (e.g., Canon iR5055/iR5065), regardless of the default selection for the output tray, the printed pages always came out of the top tray. This does not happen when using java.awt.print.PrinterJob to print a swing component. In other words, when using the java.awt.print.PrinterJob to print a swing component, the output would come out of the correct (default) printer tray as selected/pre-selected by the user.

JUSTIFICATION :
Our client has multiple users sharing the same printer and it is important for them to be able to designate different printer trays for different users to use.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
When using javax.print.DocPrintJob to print a document (not necessarily just PostScript file) on a printer that has multiple output trays, the default tray selected by the user (via the Windows printer setup interface) should be honored.
ACTUAL -
When using javax.print.DocPrintJob to print a document (not necessarily just PostScript file) on a printer that has multiple output trays, the default tray selected by the user (via the Windows printer setup interface) is ignored, instead, the printed document always came out of the top tray.
