What to Do When Your Retail POS System Printer Goes Offline

A retail POS system printer is an essential part of any retail POS system. When it goes offline, it can interrupt your entire workflow and cause unnecessary delays, especially in high-traffic environments where every second counts. Whether you’re dealing with a retail POS system printer offline issue or a temporary connection glitch, the Sunany team has put together a practical guide to help you troubleshoot the problem and get back to business in no time.

1. Check the Connection
For wired retail POS system printers, make sure the power cable is securely plugged into a working outlet and that the printer is powered on.
For wireless retail POS system printers, ensure that the device is connected to the same Wi-Fi network as your POS system or computer.
Carefully check the retail POS system printer’s IP address settings to confirm that all configurations are correct.

2. Restart All Devices
A simple restart can resolve many temporary issues.
Turn off the retail POS system printer and unplug the power cable.
Wait 30 seconds, then plug it back in and power it on.
At the same time, restart your retail POS system printer.

3. Check Printer Status
On your computer, go to “Printers & Scanners” (or “Devices and Printers”).
Find your retail POS system printer and make sure it is not set to “Use Printer Offline.”

4. Set as Default Printer
Still can’t print? It might be because your retail POS system printer isn’t set as the default printer.
Right-click the printer icon and select “Set as default printer” to ensure all print commands are sent to the correct device.

5. Clear the Print Queue
Open the retail POS system printer control panel, check the print queue, and cancel any pending or failed tasks. This will clear the way for new print jobs.

6. Reinstall or Update the Driver
Outdated, incompatible, or corrupted drivers are a common cause of printers going offline.
Sunany recommends removing the current driver from your system and downloading the latest version directly from the official manufacturer’s website.
Avoid third-party sources, as they may cause compatibility issues or introduce bugs.

7. Perform a Factory Reset (Last Resort)
If all else fails, try resetting the retail POS system printer to its factory settings.
Press and hold the reset button for 5–10 seconds, until the indicator light blinks or the printer restarts.
Sunany Technical Tip: This will erase all custom settings, including print density, speed, auto-cutter preferences, and character encoding. Be sure you’re prepared to reconfigure these or have someone available who can.
