# **1. What Does “Canon Printer Queue Not Printing” Mean?**
When you send a print job to your Canon printer from your Windows, macOS, or mobile device, the document enters a **print queue**, a list of pending print commands.

You may see symptoms like:
### ✔ Print jobs stuck in queue
### ✔ Status shows “Printing...” but nothing prints
### ✔ Multiple print tasks accumulating
### ✔ Printer shows “Offline” or “Paused”
### ✔ Canon printer connected but not responding
### ✔ No errors, but printer won’t print

When the queue stops working, no print commands will reach the printer.
