There has been some work going on emulating early Laserwriters in MAME and I was
wondering
if anyone still has boards or firmware dumps from Laserjets.
It seems most have been scrapped.

I might know where an Apple printer is, but not sure i we took it. The
one with the Laserjet 2 Canon engine.? Not what you're after, but
possibly interesting.
There seems to be a lot of cartridges turning up though.? Those would
probably be interesting as well if you had the emulated engine.

At least here in Brazil you can find supplies for HP II and III printers.
Probably for IIp and IIIp...

What? I have restored an maintained a number of early LJs. Check eBay for parts and ink.
The newer ones are actually harder to maintain because of all the DRM in the toner
cartridges and poor build quality.

I believe I still have an LJ III and might still have parts from a scrapped

I recently pulled out a LaserJet IIIp while cleaning up to make space
for a bench to work on things like dumping roms, which I'm already
behind on. Is there 4MV interest as well, btw? I have one of those
also.

My LaserJet 6MP is still going strong and is my main lab printer. I like it for retro work
because it has AppleTalk capability. I plugged my Mac SE into the network and it
automagically found it! Meanwhile Windows still doesn?t know it?s there unless you put its
nose right on it ;-)

My workhorse printer is an HP 5Si/MX. I use it mostly for music and
schematics, since it will do up to double-sided 11x17. You can still find NIB
toner cartridges on Epay, as well as fusers and other parts. It's a beast.

I have no idea what sort of effort it would take to do so, much less how
usable the dumps would be.
That being said, I can see some value in a virtual JetDirect.
Especially if it could emulate an older more capable JetDirect
(multi-protocol) that could be used by something to translate to more
contemporary printing methods; e.g. IPP. It might be an option for
older virtual machines to be able to talk to and print to contemporary
printers.

There were software updates for the firmware and I imagine they were
a complete image and not a patch. Did anyone save those?
I saved a 4si PS, a QMS 420 and an Apple Laserwriter. Others
were recycled perhaps only two years ago. One step behind
the wrecking ball or the recycling dumpster as the case may be.

Yup. I started saving Laserwriter bits when their was originally
some interest in emulation a few years ago.
HP used Canon formatters on the LW and LWII, then did their own on the LW III
with more and more HP ASICs on them. They are all 68000 based.
Looks like they switched to i960s or 29000's up through the VI.

Looks like they may be defunct now, but maybe carrying on under another
name/new management? Or if not, someone else, hopefully, may have bought
the inventory. Still a number of places selling parts for these,
anyway.

AFAIK HP did the HPII and HPIII formatters

There has been some work going on emulating early
Laserwriters in MAME
and I was wondering
if anyone still has boards or firmware dumps from Laserjets.

"nobody collects printers"
I don't know about collect but I have a soft spot for early LaserJets. I have a 4SI
and 4M+ and an original Color LJ. I also have a few Apple LaserWriters (IIgs, 600, maybe
one more).
I have tried to get my hands on an original LJ a couple of times but the deals fell
through and I did get a IIID but before it could be shipped the seller moved warehouses
and it got lost in the move. Frankly if you can't find it locally it is hard to get
them. Sort of like CRTs. If anyone in the LA Area wants to get rid of the following
I'd be interested in giving them a good home:
LJ IIID
LW 8500, Color LW, LW Pro 810
Compaq PageMarq 20 (or even a 15)
IBM 4029

I hope I know the answer, but having said that, I?m really curious as to why they?re
working on the emulation.
The only old Lasers I have are an HP 5mp I bought new, and finally retired this spring
(though I just realized it?s probably still on), and a 5p I was given a few years ago. I
was quite happy to get my VMS Cluster working with a modern HP LaserJet that is *WAY*
faster, and supports duplexing.

For the intellectual challenge, and to play with the Postscript interpreter.

Maybe an emulator for Xerox's XGP could be piggybacked onto that. The
"firmware" is PDP-11 or PDP-6 code from MIT and SAIL. It could be used
to print classical memos written in PUB, TeX, TJ6, Scribe, Bolio, etc.
