I think what is happening may be dependant on how you are sending the files
to the printer. I will take a guess that since you are seeing the 1ab3 error
then you might be sending it from a unix host or through some non standard
method. In this case there are times when an original LaserWriter might work
and a newer or different PostScript printer might fail because of some logic
in LaserPrep. There are parts that check if sertain code is built into
the printer, and if so it is supposed to "skip" part of the laserPrep file. 
In non standard communication setups this skip may fail and thus code
that is supposed to be skipped or eexec'ed (not a typo) normally will
be executed as PostScript and choke.
