Digital BW, The Print

I've got both OS X Macs and PCs (XP), and I need to share an Epson 1270 between all my 
computers. I'd love to have the printer on the network with a wireless (or wired) print 
server, but I haven't been able to tell if it would really work. The Mac and XP PC are in 
different rooms, so a USB switch is not a possible solution. It seems that laser printers are 
often in a different category, because some of the sharing schemes require the use of 
PostScript.

Has anybody succeeded in setting up something similar? What hardware did you use? 
Anthony, what operating systems are you running?

Thanks!
