Hi, I can't get any of my computers on my small network to print to any of the two printers that I have. I have one XP machine, one Vista machine, and two Macs running OSX, networked using a Linksys BEFW1154 v2 router (there's also two PowerLine XE104s in use but I'm temporarily taking them out of the picture to simplify troubleshooting). One of the Macs has an HP DeskJet 5550 attached, the XP machine has an HP Photosmart C3100. Only the attached printer/host pairs can print. None of the computers can print to any networked printer. All computers can ping each other. Since this seems to affect all the computers, I tend to wonder if there's an issue with the router... there's no advanced filtering setup going on, and AFAIK the filtering is set to the defaults. Concentrating on the one printer attached to the XP machine, I have sharing turned on for that printer, Print Services for Unix installed, and File and Printer Sharing for Microsoft Networks enabled. Both the Mac OSX and Vista machines trying to print to that printer time out. What should I try next?

sorry, don't know how this got posted to the wrong forum.
