A Canon printer not printing can interrupt your work even when the printer appears connected and ready. You may send a document, see it waiting in the print queue, and receive no output. In other cases, the printer feeds paper but produces blank pages, missing colors, or faint text.

Common causes include a blocked print queue, an offline printer setting, connection problems, empty ink or toner, and incorrect printing software. This guide explains why your Canon printer won’t print and how to troubleshoot the problem on Windows and Mac. Settings and maintenance procedures vary by model.

Why Is My Canon Printer Not Printing?

The most common reasons include:

• The wrong printer is selected in the print window.
• Printing is paused, or an earlier job is blocking the queue.
• The printer has lost its WiFi or USB connection.
• Paper is missing, jammed, or loaded in the wrong tray.
• An open cover or error message prevents printing.
• Ink or toner needs attention.
• An inkjet print head has blocked nozzles.
• The installed driver is incompatible or incorrectly configured.
• The document or application has a printing problem.

First, identify whether the printer does not start printing at all or prints pages with missing content. These symptoms require different fixes.
