I am having some trouble setting up wireless printing in my home network. I have a Dell printer connected via USB to a Dell desktop running XP on my network. I have gone on my PowerBook and set up the printer using Printer Setup Utility (Windows Sharing etc) and so I have it on my list, but when I go to print to it, It says "Processing Page 1" and I can hear the printer initializing but nothing ever prints. The Mac doesn't give me any error messages either. What's up?
