[comp.periphs.printers] PostScript Problems on HP Laserjets with PS Cartridges

I have an HP Laserjet Series II fitted with the Pacific Data PostScript
cartridge attached to my Atari Mega ST4.  Using the Spectre Mac emulator,
I have been happily using Word (and other SW) to prepare PostScript files
via the Laserwriter printer driver and the SerialPrint Desk Accessory to
print them out.

Recently a friend with the same setup invested in an HP Laserjet III with 
the HP PostScript cartridge, but we can't get the printer to produce
anything.

Using the SerialPrint program on his system, data is transferred to the
printer (and the "processing data" message appears on the control panel),
but instead of producing hardcopy, the LJ III appears to just swallow the
data.  I have checked the SerialPrint settings on both systems, and they
are exactly the same (^M for end-of-line, ^D for EOF).  A PostScript file
produced on his system will print out fine when transferred to my system.

It looks as though my PostScript clone (PacificPage) is actually working
better than the HP PostScript cartridge which has the official Adobe
implementation!

Does anyone have any idea about what might be going on here?
Thanks in advance
