The most common reason for low-quality prints has to do with a low-quality source file.

To test whether your printer is in good health, please print the Sample label.

But if only parts of your label look faded, the reason could be one of the following: 

1.Label: The darkness of the label depends on the label manufacturer. High quality labels produce darker prints. 

2.Print density and speed: Within your printer [preferences], you can set your [Density] and [Speed].

For Windows: 

You may access these settings by going to your [Control Panel] -> [Printers and Devices] -> right click on [4BARCODE...] driver-> click [Printing Preferences] -> [Options]->[Print Speed]->[Darkness]

Note: 

1.By default, your printer is set to print at its fastest. Slowing this speed will result in a higher resolution.

2.Increasing the number for your density / darkness will result in a darker print. Setting the density 

too high will result in unwanted dark lines and/or label getting too hot and sticking mid-way to the 

printer head. Decreasing this number results in a lighter print.  (Example pictures shown below)

3.Besides, to clean the print head and rubber platen roller softly with industrial alcohol-sprayed 

wet cloth also helps to improve the print quality. ( example picture shown below )

4.If the print head is broken or the rubber platen roller worn-out, the print quality also looks 

not good. ( example picture shown below ) In this case, you are suggested to replace the print

head or rubber roller.
