The SUNMI NT Series is a range of high-speed 80mm thermal desktop printers designed to handle high-volume ticket printing for retail counters, online takeaway orders, and busy restaurant kitchens. Because these printers use thermal technology, they use heat to apply text and graphics directly to the paper, completely removing the need to buy or replace messy ink ribbon cartridges.

The series is divided into two distinct models to fit your business requirements:
-
The NT311 Cloud & Kitchen Printer (KCP): Built specifically for hospitality lines and online food ordering. This model features a loud buzzer and a bright indicator light to alert staff when a new ticket arrives. Its built-in cloud printing tech allows the printer to pull orders directly from online websites and delivery platforms over the internet, printing them off automatically even if a main computer till is turned off.
-
The NT320 Receipt & Label Printer: A versatile dual-purpose unit that can switch seamlessly between standard paper receipts and adhesive sticky labels. This makes it perfect for retail pricing, barcode printing, and order labelling. It is specifically designed to fit and dock directly with the base mounts of compatible SUNMI checkout terminals.
