Have three computers (Dell 1 running xp pro, Dell 2 running vista, and Acer running win 7). Dell 1 and Acer are wired to a router (Netgear WNR2000) and Dell 2 is wireless to the same router, have a home network setup. All of the computers can see each other on the network and exchange files. The Dell 1 and Acer computers have HP printers connected through usb ports (the Acer has HP photosmart c4180 printer and the Dell 1 has HP deskjet 970cse). Both of these computers can access each others printers via the network. The problem is the Dell 2 computer cannot access either printer. I get the error message 0x00000709 when trying to access either printer. I have tried reinstalling the printers on both computers, installed printer drivers on the Dell 2 for both printers, checked printer sharing settings, etc. I need help solving this problem....thanks.
