AMT Datasouth Corp.’s Fastmark M3 and M4 battery-powered, portable, thermal bar code printers are now available with PAL programming language. Coupled with PAL, the M3 and M4 are suitable for when a printer needs to interface with legacy systems or where changing systems to support new applications is not practical. Users can interpret, translate, filter, add-to and format almost any data stream sent from any host running any application. The M3 printer is rugged and weighs only 19 ounces with the battery. The M4 can handle media up to 4.4 inches wide, and offers both Bluetooth and WiFi interfaces simultaneously. It's also available with an optional LCD. Both models offer vehicle chargers, RTC and are Windows and ZPL compatible.
