Why is the barcode or QR code on the printed label too dark to be scanned? – SVANTTO

Try to choose PDF file format for printing instead of PNG, JPG, and other image formats, when the barcode you print out is very fuzzy (please refer to the picture below).
If the barcode still cannot be scanned,The reason is that the printer's density and speed settings are not suitable for the current shipping label, we need to adjust it in the printer settings please try to reduce Density and increase Speed (Please refer to How to adjust the density and speed in the settings? for specific operation steps).
