Karl, I don't have that option on my list. How, exactly, did you get it to work? And are you using a print server? I have an HP print server (JetDirect 500X) and it handles an HP Laserjet 2100 and an HP Deskjet 960C. No problems with a wired connection from either Macs running various flavors of 9 and X or PC's running XP, but no dice with the wireless. I used to be able to print to the HP 960 wirelessly (I think) but that was a while ago and I seem to have messed things up. Never could get both of them working. I've tried just about every option under the sun, including CUPS, too...
When I get the time, I may post over at MacFixit in the hopes that John Strung will be able to walk me through it, unless one of you here has the magic potion!
BTW, my D-Link wireless router doesn't have a built-in print server, though I've read that the ones that do only work with Macs printing to a Postscript printer.
