changed my operation system from win 7 to win 10 before installing antivirus Nod 32... my installed printers were working including cannon. (Having 3 printers on my system. Hp - Cannon - Richo copier).
some conflict with canon... scanner is working but the printer driver is now having a problem .. tried to download the latest one. Still, the printer driver is not ok... some errors for NT 4.0 block, etc coming... any solution for this .. or should I reinstall my operating system.
Turn off the anti-virus and see it that resolves the issue. If so, see how to configure the AV software to accommodate the printer.
