choose tray in postscript printing created by oracle

[Gerald Taylor]

Hello we have an HPUX 11.00 server running:
Oracle 11.5.7
Oracle Reports 6i
We basically want to choose the tray when printing to a hp 8100 printer. There is a option arguments command in the oracle setup that allows us to issue a lp command but the "-otray3" options does not work and the jobs always pull from tray2. The "-o tray3" options works when it is issued from command line but not with oracle created postscript files. Does anyone have experience with this situation or can offer some help?
