The K3 is designed to keep busy checkout lanes moving while making routine paper changes quicker and easier. Its paper handling and connection choices also simplify deployment into existing POS systems.
Built by POS-X’s parent company Custom, the K3 is a substantial retail printer for receipts, coupons, kitchen slips, invoices, and tickets.
Capacitive controls make paper feeding, cover release, and status checks quick. High-resolution output keeps logos and coupon barcodes sharp, while paper-saving features and larger-roll support reduce routine paper changes. The active listing includes a four-year manufacturer warranty and lifetime POSGuys support.
