If your Canon printer shows a job but nothing comes out, work through these quick checks before calling for repair. First, open the print queue on your computer, cancel every stuck document and try one fresh test page. Next, restart the Print Spooler service: press Windows+R, type services.msc, find Print Spooler, and choose Restart. Then run a nozzle check from the printer menu or driver utility; if lines are missing, run one cleaning cycle. Finally, remove each ink cartridge, reseat it until it clicks, and make sure the protective tape is gone. Still stuck? Here is our full Canon printer not printing fix with screenshots and error-code notes.
