Here is another tip that may help you debug your case (and some other
ones you may encounter in your future admin career :-)  ):

 (1) go visit http://techbase.kde.org/Projects/KDEPrint/Tools%2BUtilities
     and fetch one or both of the CUPS backend scripts "2file" and "2dir".

 (2) install a virtual printer using your PPD and one of the backend
     scripts so you can "print to file" with them.

 (3) in cupsd.conf, insert "PreserveJobFiles" and restart cupsd.

 (3) print to the new printer.

Now you'll have 2 files on disk:

 (a) the file as was handed to CUPS by OOo in /var/spool/cups/d000NN

 (b) the file as it was changed by the CUPS filtering chain, according
     to your overall print settings.

Now you can look at the differences of the two files, using

  sdiff -sbB file1 file2

You'll probably notice that CUPS does insert non-empty PostScript code
to address the tray selection, while OOo does a fake job on it.

If that is confirmed, submit a bug report with the OOo folks.
