Trusted (TIJ) thermal inkjet printer range
Gx-Series thermal inkjet printing solutions are versatile, easy to integrate, easy to operate - the perfect fit on many printing applications and substrates. With the latest networking technology and producing graphic code quality, the Gx-Series TIJ printers are ideal not only for batch and date coding but also for complex code formats, check weighing and track & trace applications across FMCG industries.
The new range, with the exception of the G50i, is fully compatible with Industry 4.0 standards using the Domino Cloud. Domino Cloud allows remote capability, providing the data and tools to ensure printing is a contributor to better packaging and processing systems management.
If you are looking for a coding solution that is designed for high-resolution printing at high line speeds with complete reliability Gx-Series TIJ printers can meet your needs.
Enabling Smarter Packaging with High‑Quality 2D Codes
Retailers and producers are adapting packaging to support inline variable 2D code printing to meet GS1’s Sunrise ambition for point of sale (POS) adoption, Digital Deposit Return Schemes, consumer engagement and taxation requirements. So reliable, verified QR/Data Matrix codes are essential.
The Thermal Inkjet Gx-Series PRO delivers high‑resolution, GS1‑compliant 2D codes at production speeds, supporting compliance, traceability and operational efficiency.
Clean. Clear. Coding.
- Graphic printing quality on paper, card, plastic, metal and other materials
- Flexible label design: text, counters, clocks, graphics, logos, barcodes can all be included on the same label
- Grade A code readability (ISO 15415) using Domino's inks on high-density data matrix codes
Gx-Series Range
If you need a coding solution engineered for high‑resolution printing at fast line speeds, meet Domino's thermal inkjet printer (TIJ) range - the Gx‑Series. Featuring the Gx150i, Gx350i and Gx-OEM printers, they are all fully compatible with Industry 4.0 and can integrate seamlessly with the Domino Cloud, enabling remote connectivity and control.
Gx-Series PRO - Supporting 2D Coding
As GS1‑powered QR codes become standard, print quality and first‑time scan rates are critical. Domino’s Gx‑Series PRO printhead delivers high‑quality variable coding you can rely on. Combined with Domino Automation and Vision Systems, it provides a fully integrated solution that boosts productivity, reduces waste, and maximises uptime.
Helping you achieve compliance

Fast moving consumer goods
For the variety of coding requirements within the FMCG sectors, Domino has developed an ink range that is suitable for all packaging levels. From flexible films to porous shelf-ready packaging and shipping boxes.

Life sciences
Legislative requirements call for unique item-level identification. Gx-Series printers ensure coding in compliance with pharmaceutical regulations (e.g. EU FMD, US DQSA) according to GS1 standards and can be included in a 21 CFR Part 11 validated system.
Electronics and industrial
Gx-Series prints lasting, rub and scratch resistant codes, logos and graphics on electronic components, metal, aluminium or PCBs. Rapid dry times and good adhesion deliver optimum performance on fast-paced production lines.
