I have a Canon Pixma 495 on both my computers which are all located in one room on the same wireless network. Both were working fine for years. Yesterday the printer had an error message about low ink. Tried changing cartridge but didnt work. I tried to diagnose it but it said it could not detect the printer on either computer. So I tried to reinstall the drivers on one of the computers. Won't let me as cannot detect the printer. Changed the ink catridge again and now the printer prints just fine off the computer that I didn't try to reinstall the drivers on. The other computer cannot use the printer as it still cannot detect it. I tried disengaging the firewall. Did not help. I tried turning off both the router and the printer. Did not help. How do I get the main computer to detect it again? So incredibly frustrating!
