In a busy restaurant, POS printers play a critical role. They send orders to the kitchen, print customer receipts, and keep operations running smoothly. When a printer stops working, orders get delayed, staff get frustrated, and customers are left waiting.
The good news is that most POS printer problems are simple and easy to fix—if you know where to look. This guide explains the most common POS printer issues in restaurants and how to troubleshoot them quickly without needing a technician every time.
1. Printer Not Printing at All
Common causes:
- Printer is turned off
- Power cable is loose
- Network connection issue
- Printer not selected in POS settings
How to fix:
- Check that the printer is powered ON
- Reconnect the power cable securely
- Restart the printer and POS system
- Go to POS settings and confirm the correct printer is selected
💡 Tip: Always restart the printer first—it solves many basic issues.
2. Paper Jam or Paper Not Feeding
Common causes:

- Torn paper inside the printer
How to fix:
- Open the printer cover

- Dirty print head
How to fix:
- Flip the paper roll and try again

How to fix:
