Hi,
If you're after a mono laser, anything that has native PostScript support will work well.
I use a
Lexmark e250dn. It has native PostScript support, and the PPD driver for Linux is easily obtained to allow the CUPS/Linux printing system to give full access to the printer's options.
It's a decent price (or at least it was in New Zealand!) and has full duplex support, very quick and high quality printing, very quick 1st page startup time and both USB and Ethernet interfaces.
Oh, and it'll probably work fine with an Amiga too, given a standard PostScript driver!
For inkjets, it's probably best to look at the
CUPS web site to check compatibility before buying.
