Replacement Print Head for Zebra Printers

This thermal print head replaces OEM part 105934-037 in Zebra ZP450, ZP500, ZP505, ZP550, GK420D and GX420D direct thermal printers. It restores crisp barcode and shipping label output at 203DPI resolution for warehouse, logistics and e-commerce fulfilment operations. Buyers needing higher-resolution printing or thermal-transfer capability will not be served by this fixed-resolution direct-thermal component.

Plug-and-Play Installation

The head follows the original dimensional standard and uses gold-plated contact pins that match the printer socket, so replacement follows the maintenance manual without special tools. Misalignment during seating can cause missing dots or vertical blank lines, and the anti-wear coating requires a clean platen roller to achieve full service life. Installers who skip the manual's cleaning steps often see premature print-quality loss.

Compatibility Check Before Ordering

Verify the printer model label matches one of the six listed Zebra models and confirm the existing head bears part number 105934-037. Ensure the printer uses direct thermal media only, as this head does not support thermal-transfer ribbons. Sites running continuous high-volume shifts should also inspect the platen roller and drive gears for wear before fitting the new head.

Questions about this item

How do I confirm the 203DPI print head is working correctly after installing it in my Zebra ZP450?

It fits ZP450, ZP500, ZP505, ZP550, GK420D and GX420D direct thermal printers.
