Since it looks like you've got a Windows only printer ... heres a slightly clunkly workarround. Just print to a .pdf from the Mac, transfer the file to the PC (or save to a network drive), and print from the XP machine. It's clunkly yes, but it'll save you from buying a new printer or other hardware. Ideally the XP machine would be able to open/print/delete files automatically as you pass them over ... but I'm not familiar enough with Windows to reccomend a way to do that.
