9-Pin dot matrix printer aimed at general administration - particularly reception areas and applications that can use flatbed feed such as airline and finance counters.

  • High durability 24 pin head with a 200 million character life
  • Parallel interface as standard
  • RS232 Serial version available
  • 2 million character ribbon life
  • Up to 5 part forms, 1 original and 4 copies

The ML390FB appears in a 9 pin version as the ML320FB - the simpler head gives somewhat faster printing but obviously at the cost of print quality. Resolution is only only 240 x 216 dpi on the ML320FB and 240 x 360 dpi on the ML390FB. Otherwise the two printers are very similar.

The ML320 and ML321 are more conventional dot matrix designs designed for rear and bottom feed.
