To clear the memory on a thermal POS printer, follow these general steps. The specific process may vary depending on the model, but this should give you a good starting point:
- Turn off the printer.
- Press and hold the feed button (sometimes referred to as the “paper feed” or “advance” button) while the printer is powered off.
- Turn on the printer while still holding the feed button.
- Release the feed button after a few seconds (usually 5 to 10 seconds). The printer should perform a reset or clearing operation.
- Once the process is complete, the printer might print a test page or reset to its default settings.
If this doesn’t work, you may want to consult the user manual or contact the manufacturer for model-specific instructions. Some printers also have a reset option in their settings menu if they have an LCD display.
