Barcode and QR code printers for packaging lines
Print machine-readable barcode and QR code data as part of a packaging line, label process or flexible film application.
Application guidance for traceability code printing.
How to specify this coding application
Barcodes and QR codes need more attention than simple date marks because print contrast, quiet zones, distortion and substrate compatibility affect scan quality. Thermal inkjet and thermal transfer overprinting can both support coded data, but the best option depends on the packaging format and line process.
- Code type and required grade
- Code size, quiet zones and orientation
- Material contrast and background colour
- Variable data source and message management
- Line speed and printhead distance
- Verification, scan checks or reject requirements
Recommended coding routes
Use these routes as a starting point before confirming samples, speed, substrate and integration details.
Labels and cartons
Thermal inkjet can print barcodes and QR codes on suitable label and carton applications.
Film, bags and pouches
Thermal transfer overprinting is usually the better route for high-resolution codes on flexible film.
Unique product identification
Print-and-apply systems can be considered where each pack needs a unique label or address label.

Traceability code printing FAQs
Can coding machines print QR codes?
Yes. Thermal inkjet and TTO systems can print QR codes where the print area, data handling and substrate are suitable.
Can hot foil print barcodes?
Hot foil is intended for simple character-based date and batch marks, not complex variable barcode or QR code printing.
Which printer is best for GS1-style data?
That depends on code size, substrate, scan grade and line setup. TTO or thermal inkjet may be suitable after checking the application details.
