I would conservatively estimate your chances of making this
work to be Zero, especially since you lack anyone who can
rewrite the LaserPrep file almost in its entirety.

The Apple LaserPrep file is a fiendish exercise is writing bad
PostScript; it is about as cuuningly and unnecessarily
non-portable as I can possibly imagine. Your problems will get
rather worse once you start hitting the eexec routines.

To have any chance with this stuff you will need to contact
Imagen and ask them how they justify having an AppleTalk
interface on their printer if it can't print Apple output: they
may have a new installable dictionary to side-step the latest
Apple trickery...
