Permanent residence is not required.  Simply comment out the line
which calls 0 exitserver in the LaserPrep prologue.  The call to
setsccinteractive near the beginning should also be commented out (vintage
LaserWriters choke on it).  

Non-Apple PostScript (e.g. QMS) printers may choke on the format of the
LaserPrep file created by versions 4.x (and maybe 5.x as well, haven't had the
opportunity to check): they seem to choke on the hexadecimal code for
smoothing.  Maybe eexec or cleartomark behave differently.  I have not tried
modifying the file to put the big hex strings on the stack and doing thee
eexec after that.

Has someone managed to get a QMS to print downloaded Macintosh files?
