Blank Printing Results
1. Check the Print Head
Open the printer cover, remove the paper roll, and check if the print head is jammed by labels or foreign objects.
2. Check Battery Power
Try using a fresh set of alkaline batteries. If the voltage is insufficient(Recommended power for printing is higher than 25%), the printing results will be affected.
If your P12 printer has a Type-C port, you can remove the batteries and connect it using a 5V-2A plug or cable.
3. Use Different Tapes
Try printing with other types of tapes.
4. Perform a Self-Test Print
Turn on the printer and quickly double-click the power button to see if you can print a self-test page. If the self-test page prints normally, it may be that the data transmission between the printer and the mobile phone is not good, you can try to print from another mobile phone.
Unclear Printing Results
1. Do not use the plug-in and dry battery simultaneously, as this can cause voltage instability and affect printing quality. If the dry battery is out of power, the printing effect will also be poor.
2. If your P12 printer is low on power, the printing effect may be poor. Recommended power for printing is higher than 25%.
3. If your P12 has a Type-C interface, unplug all dry batteries and use a 5V-2A charging head to connect it (the P12 is not a rechargeable model and can only be used while plugged in).
4. Wipe the print head with an alcohol cotton swab. If there is any foreign matter on the print head, the print will not be clear.
