Printing to HP LaserJet from SunOS

I've been able to print Postscript files to an HP LaserJet 5SiMX printer on my network using either the lp or lpr commands on my SunOS.  The plots I've made have all been on 8 1/2" x 11" (A-size) paper. This printer has an upper and lower tray as well as a manual bypass tray on the side.  The bypass tray is loaded with B-size paper. I'd like to plot B-size postscript files on this plotter usingthe B-size paper in the bypass tray. I believe that I need to embed the appropriate 'paper source select' command *in* the postscript command stream I send to the printer. I don't have the manual for the HP Laserjet so I need to know what command to embed to make the plot go to the bypass tray.

you have to use PCL command (even if you want to print with PS). To select the paper source, you have to send: Ec&l#H
Ec is escape (27h) and # could be :
0 : paper source remains unchanged
1 : Feed paper from a printer-specific tray
2 : Feed paper from manual input
3 : Feed envelope from manual feed
4 : Feed paper from lower tray
5 :  Feed from optinnal paper source
6 : Feed envelope from optionnal env. feeder

You, perhaps, need reset the printer before:
Ec%-12345XEcE then set the paper source, send your PS file then EcEEc%-12345X
