Not with this model - the 4M and 4ML use the same case and engine (and
look identical from the outside), but under one of the cord cover bays
is a Mac-pinned RS-422 8-pin minidin which is either at the edge of or
is cabled to an extra board that the 4L does not have.  The extra
board is a Postscript engine and font ROMs.

I believe it would be possible to turn a 4L into a 4ML by adding the
extra goodies, but it is nothing like its contemporaries that were
mostly lacking a ROM SIMM with Postscript and/or Adobe fonts on it.

The 4ML will even talk out both ports - the Mac port to a Localtalk
network, and the parallel port to a PC or Amiga or whatever.  I used
to use that feature to my advantage when I would run a Mac emulator on
my Amiga (with add-on Mac serial ports and Localtalk).  The printer
was smart take a job from one port and hold the other port off until
the first job was done - no printer switch necessary.

Yes I like larger HP printers, but for something that only takes up
the corner of a desk, the 4ML is really nice.
