Gprinter GP-3120TUC 3-inch (80mm) Direct Thermal Barcode & Label/Receipt Printer, USB

The Gprinter GP-3120TUC is a 3-inch (80mm) direct thermal printer that works as both a barcode and label printer and a receipt printer, which makes it one machine for pricing tags, shipping labels and counter receipts. Because printing is thermal, there is no ink, ribbon or toner to replace: the only consumable is paper, and running costs stay predictable. Print resolution is 203 dpi, sharp enough for small barcodes and fine label text, and speed runs from 2 to 5 inches per second, up to 127mm/s. It takes a print width range of 25-82mm with a maximum roll diameter of 115mm, so the same unit handles narrow product labels and wider receipt rolls. Onboard memory is 2MB DRAM plus 2MB Flash, while automatic paper detection, automatic calibration and overheat protection keep long unattended runs from going wrong. It connects over USB and works with common label design and POS or inventory software. It suits shops, pharmacies, courier desks and small warehouses that need product tags and customer receipts from a single machine on a crowded counter. At 1.4kg it stays put on a desk yet is light enough to carry between a stockroom and a till, and USB connection means an ordinary billing PC drives it with no network setup. Automatic calibration earns its keep when you switch label sizes several times through a busy day.
