Datamax offers two different printers that support the UHF band; the A-Class print engine for printer applicator integration, and the new H-Class. These printers are ideal for achieving compliance with mandates from large retailers and purchasing organizations, as well as economical enough for those users developing closed loop applications to streamline internal processes. These RFID-UHF printers support EPCglobal and ISO standards for Ultra High Frequency (UHF) applications including Gen2. The robust multi-protocol RFID tag encoder in these printers is capable of performing multiple procedures, including writing data to RFID tags, querying the tags unique identification number, and auto calibration of the tag to ensure no valuable RFID smart labels are wasted. The RFID printer option must be specified at the time of printer order.
