Use the direct thermal or thermal transfer printers in connection with another printer, thanks to ZPL support. Serial RS-232 and USB ports are integrated, standard. Optionally expand the spectrum with an Ethernet 10/100 print server or 802.11 a/b/g/n Wi-Fi, as well as a parallel interface, standard on board, or manually from the outside. All of the models feature robust housing and boast a compact footprint. The media cover on the ZT230 is also made of metal; on the ZT220 it is made of shock-resistant plastic. The double-folding cover has an opening radius of roughly 10 cm, whereby the entire printers size is compressed enough to require little location space. Changing the colour ribbons and label rolls is easy, simply open the cover and replace without any bothersome threading. Plus, the ribbon capacity is approximately 450 m. The view window always gives you a quick look at the material status. A high print quality for barcodes, words and graphics is guaranteed by the resolution of 203 or 300 dpi. Plus, enjoy the proven Zebra quality when it comes to tools-free access and maintenance of the standard components, like the printhead and roller. To maintain or repair all other parts you only need three common tools. The display of the ZT230 and the colour touchscreen of the ZT231 support the printers intuitive handling, simplify voice commands, as well as control the printer properties. Additional LED displays provide the user with information about print status and maintenance needs. Even unschooled personnel can intuitively operate the printers of the ZT200 Series. The lighted and movable media sensor is also viewable through the inserted media, for optimal positioning. Coloured markings on the inside further simplify its handling.
