New Printhead Print Head for Zebra GX420D GK420D ZP450 ZP550 ZP505 ZP500 Printer 203dpi PN 105934-037

Used this to replace the printhead on our GK420D thermal printer that was going out and this makes the printer print like new again. The print quality actually looks a tad sharper now. Easy to install, just look up on Youtube, took less than a minute to swap out.

Works as designed

Simple YouTube video from zebra changed it in seconds great fix for reasonable price.

Got the item, it did not look the same as the genuine Zebra OEM print head that I pulled out of the GK420d printer. I began to suspect the part. It installed easily enough, and worked for a few days and about 50 some prints with no issues, But after a week it started printing so dark that the lines on the labels had a heat bleed to them and the barcodes printed by the print head were unreadable by any of our barcode scanners. I had to put back in the old original print head that would print with lines missing because at least SOME of our labels could be scanned with the failing old print head. This "Genuine" part was useless to us, so I purchased a REAL GENUINE OEM print head from an official Zebra Partner, and returned this piece of junk.

These are a lighter print than the standard OEM ones but are a good price. If your customers are okay with the light print these should not be a problem. Easy to replace and good fitment for the wires when they connect. No issues yet and are much cheaper than OEM.

Brought the Zebra printer back to life!

Works great. I just put it in, turned it on and starting printing.

Product came in seemingly good condition. Did not work for my ZP505 or ZP450 thermal printers. Pretty bummed.
