The Zebra ZP450 is a current generation Zebra Desktop monochrome direct thermal printer originally manufactured for UPS shipping. This printer includes an adjustable bracket on the inside of the printer so that labels smaller than 4 inches can also be used. With the added memory and higher speed, up to 6" per second, it replaces the classic desktop 2844 when following our basic setup instructions. We recommend installing this printer as the standard Zebra GK420D. It is compatible with all of the programs we've tested that take advantage of Zebras EPL and EPL II programming languages.
