Most of the time I'm printing from a PIII450 which runs FreeBSD
4.8-release and an Alpha which runs 4.7-release (I know I should upgrade
but that's another issue :)). The printer is connected to a small network
at home, three computers all running FreeBSD and the printer, all
connected to a switch. Sometimes I plug a laptop from my work into the
network, which runs Windows 2000.

Now I think that the data sent to the printer is PostScript and not PCL
(if this is possible, I'm no expert on this but I guess that's the reason
Windows is printing a lot faster) and that I should install a so called
"PostScript emulator DIMM". Problem is that these are hard to find since
the LaserJet 2100 is an old model now.

I just got a tip on the mailinglist that they are still being sold at Now I hope that they deliver to Europe also
and that the company can be trusted...

	No matter what the anticipated result, there will always be
someone eager to (a) misinterpret it, (b) fake it, or (c) believe it
happened according to his own pet theory.
