Can you make the first page print from a different tray?

[Adam Nielsen]

Hi,

I'd like to create a "virtual printer" in CUPS, which I intend to make available to Windows clients.  When print jobs are sent to this virtual printer, the jobs should be forwarded to another CUPS printer but altered, so that the first page comes out of tray 1, and the rest of the document comes out of tray 2.

Is this set up possible?  I already have the printers working through CUPS (they're all network printers that support PostScript) and all print jobs come in as PostScript.  I'm only stuck on the "virtual printer that fiddles with the tray settings" :-)

Any ideas?

Thanks,
Adam.
