I am working on an HP DeskJet 3050 wireless printer linked via WiFi to 2 laptops. I have one issue. One laptop Dell 700m working on windows XP Pro. The other laptop, a Dell XPS 15, working Windows 7 64-bit.The printer works absolutely reliably from the windows XP system. From the XPS 15, the printer workings reliably for a day or so, after that the symbol indicating the printer is offline. Even in this state the printer's IP address has not altered. However the printer is still reported as offline for printing by Windows. This issue is very irritating. I have done Google searches on this issue. Even though I have found a variety of similar reports for a variety of brands of wireless printers on windows Vista or Windows 7.but no help so please assist me. Any suggestions would be appreciated.
