How To Deal With Thermal Printer Couldn't Print
First, the printer prints out fuzzy or missing words
1. Check the power supply to ensure that it is the power supply specified by the manufacturer.
2. Check if the paper size meets the printing requirements.
3. Check if there is any foreign matter such as dust on the thermal head and remove it.
4. If there is a missing word or punctuation in the printed ticket sample, you can directly check whether the thermal head is dusty. If it still cannot be eliminated after cleaning, you may need to replace the thermal head or motherboard to directly contact the relevant sales Department of after-sales.
