zebra gk420d printhead
Resolution: 203/300 dpi
Printing Method:Thermal transfer
Interface Type: Usb
The most important and delicate part of any thermal transfer printer is the printhead. To live a long life, it needs to be carefully maintained and cleaned frequently. Unfortunately, we frequently come across printheads that have been ignored, and the majority of print quality issues are actually a direct result of poor printhead maintenance. This print head was a direct replacement for the failing printhead in GK420d/GK420T Zebra printer. The main drawback is that printheads may be very expensive as well, and you don't want to keep spending money on them because a printhead hasn't been cleaned frequently enough! A printhead needs to be installed correctly and maintained regularly to ensure a long service life for your printer because it is a consumable that wears out over time (much like the brakes on your automobile). Zebra's replacement parts and printheads are quality components made to Zebra's exacting engineering standards. These cost effective components ensure that your printer will continue to provide the quality, reliability,
