I'm sorry about the issue. Does the Windows computer have windows xp, vista, or 7, or 8, or 8.1?
- Disconnect the power cord(s) from the internet/wireless modem/router device(s) for a few minutes, then reconnect
, then turn off printer, then disconnect power cord from it for a couple of minutes, then reconnect.
- On the Windows computer, go to Control Panel -> Programs / Programs and Features (or Add/Remove Programs), and uninstall any Canon driver / program you see there.
, then restart the computer.
, then go to Control Panel -> Printers (or Control Panel -> Devices and Printers) and if you still see any Canon printer, then right-click on it and remove it for now.
- On the Windows computer, download / install the MG2900 series Full Driver & Software Package at the Canon website:
; make sure to select the Wi-Fi/wireless option when prompted during installation.
- If the Windows computer is able to print, then on the Mac computer, click on the Apple logo / menu, then System Preferences, then Printers & Scans (or Print & Fax), then select the Canon printer there, and then click on the - (minus) button at bottom left, and remove it for now.
, then click on the + (plus) button at bottom left, and it should detect the Canon wireless printer, then add it. Then check printing.
