Citizen CT-S310II Reviews

POSGuys Rating:

The CT-S310II is a fabulous step towards an environmentally friendly POS industry and should satisfy most receipt printing requirements. It is priced very close to traditional printers and as such, is a most affordable green POS printer. It must be noted that the CT-S310II is average where speed is concerned but 6.3 inches per second is quite sufficient in most cases.
