They probably aren't escape codes.  They are probably AMIGO or CIPER bus
secondary commands.  Indeed, I suspect they are the commands that DISABLE
recognition of certain escape sequences in user data (like, unfortunately,
<ESC>E, which is hard-reset).  The 3000 print spooler intercepts, validates
and converts user sequences to bus secondaries.  This is to prevent users
from messing up the printer configuration for the next job.  Compared to
HP-UX, MPE is slightly paranoid in this regard.

You will probably need to have your HP-UX spooler make a DIL library call
and emit the appropriate bus secondaries to enable escapes and then put the
printer back the way you found it after each job.  I can't find the needed
reference material in my library.  You'll need to have your SR or SE contact
Network Printer Division in Boise, ID, and request info on the CIPER command
set and/or the underlying AMIGO protocol.

It is also possible that some obscure printer configuration parameters are
different for MPE and HP-UX.  Bottom line:  this won't be trivial.
