The Zebra GK420t monochrome desktop direct thermal/thermal transfer label printer comes equipped with an Ethernet port, prints 5" per second at 203 dpi in a single color, and can be used to print labels, tags, receipts, or other media up to 4.09" wide. This middle level desktop printer can serve as a direct thermal printer, which heats thermal paper to produce the print, or as a thermal transfer printer, which heats a ribbon to produce the print on the paper. Direct thermal/thermal transfer printers use heat instead of ink and are typically smaller, quieter, faster, and more energy-efficient than dot-matrix printers. The GK420t has a maximum print speed of 5" per second at 203 dpi (dots per inch) and prints labels up to 39" long. The 32-bit processor combined with 8 MB of SDRAM memory and 4 MB of flash memory offers faster first label printing with extensive media graphics. The Ethernet port enables the printer to be connected to a wired computer network (Ethernet cord sold separately). A USB port and an included USB cable provide connectivity to a computer or another device. EPL and ZPL programming languages are standard.
