Why is the printed label not clear?

MUNBYN Leo

Try to choose PDF file format for printing instead of PNG, PIG, and other image formats, when the barcode you print out is light (please refer to the picture).
If the font is still not clear, please try to increase the density and reduce the speed. (Please refer to "How to adjust the density and speed in the settings?" for specific operation steps).
If it is still not clear for the label, you can wipe the print head with alcohol wipes or wet tissues. (Please refer to the "How to maintain the print head?")
