Fitted with an internal rewinder, GPIO/serial card, and LAN connectivity, the Datamax-O'Neil PAC-00-48400A04 is a direct thermal label printer built around 300 dpi resolution and a maximum print speed of 10 in/s across a 4.27-inch print width. The internal rewinder distinguishes this configuration within the Performance P1125 family, pairing with auto-feed media loading and support for rolls up to 8 inches in diameter, labels up to 4.65 inches wide and 36 inches long, and a broad media range covering die-cut, continuous, notched, perforated, fanfold, ticket stock, synthetic media, and tags. Serial, USB, and Ethernet interfaces are standard alongside the GPIO/serial card, with 64 MB of onboard memory and PCL printer language enabling cross-platform compatibility on PC and Mac. The 41 lb chassis measures 11.9 in tall, 10.8 in wide, and 18.7 in deep, and the unit is backed by a one-year limited warranty.
