I have a Mac g4 running OS X 10.3 and have a local printer (Brother HL 1435 laser). I've shared the printer and also have Windows sharing activated. I have a Windows XP machine and have set up the printer as a network printer. From the windows PC I am able to see the printer and when I send a job to print everything looks like it is working fine but the page never prints. I am able to print no problem directly from the Mac to the printer, but cannot print from the Windows PC even though the printer shows up in the printers list. I am able to share files back and forth between the Mac and PC.
