12.7 mm thermal inkjet printer

About 12.7 mm thermal inkjet printer

A 12.7 mm handheld printer (also called a handheld inkjet / thermal inkjet coder) is a portable printing device designed for on-the-spot marking and coding on products, packaging, boxes, bottles, pipes, metal, plastic and more. Theyre widely used for printing:

• Batch codes, serial numbers

• Manufacturing / expiry dates & times

• Barcodes / QR codes

• Logos, text, counters

• Product identifiers on different surfaces

These devices use inkjet technology (often TIJ Thermal Inkjet) which ejects ink through tiny nozzles, giving sharp, high-resolution prints up to 600 DPI and a print height up to 12.7 mm (roughly 0.5).

They are portable, battery-powered, and allow printing without a PC (many have built-in screens & templates) ideal for factories, warehouses and small businesses. 

How These Printers Work

Most handheld printers combine:

• Battery power for mobility

• Thermal inkjet (TIJ) print heads for quality prints

• Touchscreen or onboard controls (some with USB or wireless)

• Multiple ink options (solvent-based, water-based, special inks)

• Support for texts, dates, 1D/2D codes and logos without needing a PC

You typically load an ink cartridge, choose or edit your print job on the device (text, codes, dates), and press the trigger while moving the printer across the surface for marked output.
