The SATO WS4 Series of 4-inch desktop thermal printers are feature-rich, affordably priced with great production throughput. Available in Direct Thermal (DT) or Thermal Transfer (TT) the WS4 offers exceptional print quality at either 203dpi or 300dpi with print speeds of up to 6 ips. Flexible and versatile, the WS4 boasts a ribbon capacity of 984 feet minimizing the amount of required ribbon changes. When integrated with its optional External Media Stand, both ribbon capacity and use of industry standard 8-inch outside diameter media rolls, the WS4 significantly expands its functionality to what is normally present in larger tabletop printer models at a fraction of the price. The WS4 has a straightforward replacement of its print head or platen roller so it can quickly return to full operation when normal maintenance is required. Designed with connectivity in mind, the WS4 printer has USB, RS232 and Ethernet interfaces standard. It also features optional Bluetooth or 802.11 WLAN communication interfaces further expanding its versatility.
