My parents have an XP desktop and two Macbooks. I would like to set up the network so that they can both easily print and store files on the XP pc. I installed Bonjour on it, thinking the connected printer would then show up in the Printer Setup Utility, but no luck there so far. I've tried using the "more printers -- Windows printers" but the network I set up on the XP pc doesn't even show up. I've done this before but can't seem to make it work this time. What is the easiest and most reliable way to set up an XP machine as a print/file sharing server for Macs?
