Do you mean the SIMM that makes it speak PostScript, or the other
thing? (I think there's another thing. My 4M is a few miles away at
the moment.) hat PostScript SIMM goes in the same row of sockets as
the regular RAM SIMMs.

Exactly. The firmware and RAM apparently share the same memory space.


And again, when I pulled and reseated the firmware memory card --
that fixed it.

I used to send PostScript to my 4M and let the printer interpret it.
With complex print jobs, this led to some *long* wait times before
the first page came out. I finally got the brain wave that, unlike
when the 4M was new, my PC now has about a zillion times more
CPU [speed] than the printer. So now I let the PC render the PostScript
and just send bitmaps to the printer; that works a lot better.

There is a checkbox somewhere for "print as bitmap", but I can't find it. I
would prefer to let the printer handle. I only used this feature when I had to
print a 200-page document with graphics.


Curioser and curioser... Perhaps the contacts need a bit of ProGold?

Or there is some other solder joint on the board that gets flexed when
you cycle the firmware card.

I'll keep that in mind.
