3.5 Dump mode
If the label settings do not match the printer output, you can switch the printer to dump mode to check whether an error
has occurred during the transfer between printer and host computer. In dump mode, the unprocessed raw data are sent to
the printer and printed. This function allows you to quickly check if all data is sent to the printer correctly.
Here is how you switch to dump mode:
1. Switch off the printer.
2. Switch on the printer while pressing down the FEED button.
3. You will hear 3 beeps first and then one beep later. Release the FEED button after the last beep.
The printer will automatically print "DUMP MODE BEGIN". That means the printer is now in dump mode.
4. Send commands to the printer and check whether they match the printer output.
To exit dump mode, press the FEED button. The printer will automatically print "OUT OF DUMP MODE" and switch to
standby mode. Alternatively, you can switch off the printer to exit dump mode.
