My old Deskjet 712C bit the dust (it's probably still fixable to some degree if you're interested), and my wife has never been pleased with the partially-working scanner we got from who-knows-where, so we broke down and got a Samsung SCX-4100 monochrome laser printer+scanner/copier.

We didn't just pick this out of the blue of course, I did some research on what would be a good but affordable printer for linux. First stop, linuxprinting.org's suggested printers page. This printer wasn't mentioned by name, but they did recommend Samsung laser printers as a possibility. This printer was available and the price was right on NewEgg, so I googled a bit and found Shane's post and the many helpful comments. What a small world. The comments got more and more encouraging as the page (and time) wore on, and I concluded that it would be a good printer for linux.

It arrived maybe half an hour or an hour ago, and it's already working perfectly as a printer, scanner, and copier. Anyone who's fussed with printing in UNIX before will confirm that this is very good indeed. I ran Samsung's latest drivers for linux installer (dated 2006-07-19) and it installed without a hitch. I then replaced the /usr/bin/lpr symlink back to the original non-GUI version. That's it. No Qt problems, no messing with kernel modules (I'm using USB, parallel may be a different story).

I'm running Debian testing (etch) and a vanilla 2.6.14 kernel.

Kudos to Samsung for recognizing and supporting linux, and for providing good drivers (after some growing pains), and kudos to Samsung for making a multifunction laser that's affordable.
