Quick answer: Choose a handheld thermal inkjet (TIJ) printer when the work requires mobility, changing quantities or coding cartons and products at different locations. Consider an inline system when products move consistently on a conveyor and the same coding process must be repeated. The final decision should be based on the actual product sample, required print size, operating speed, substrate and suitable ink.

What should you confirm before comparing printers?

Start by defining:

• The information to print: manufacturing date, expiry date, batch number, text, logo, barcode, QR code or serial number.
• The available print area and intended code position.
• The actual substrate, including any coating, oil, moisture, dust or surface treatment.
• Daily quantity, conveyor speed and frequency of message changes.
• Conditions after printing, such as handling, abrasion, refrigeration or cleaning.

These factors are more useful than choosing a printer only by price or maximum resolution.

Handheld or inline TIJ?

Operating condition	Option to evaluate	What to test
Large products, warehouse stock or several work locations	Handheld printer	Hand movement, positioning and consistency between operators
Products moving steadily on a conveyor	Inline TIJ system	Sensor, printhead distance, speed, mounting and print triggering
Changing quantities or short production runs	Handheld or flexible configuration	Setup time, message changes and practical operating cost
Repeated codes in a structured production flow	Inline system	Code position, product flow and handling of missed prints

Some handheld models may be evaluated with specific accessories or mounting arrangements, but the configuration is not identical for every model. PTS should confirm the proposed printer, accessories, sensor and installation method.

Choosing between BENTSAI 6205 and 6210

BENTSAI 6205 can be evaluated when a print height of up to 12.7 mm is sufficient. BENTSAI 6210 can be evaluated when a print height of up to 25.4 mm is required. A larger print height is not automatically better; the code should match the available space, viewing distance and operator workflow.

Barcode and QR-code performance also depends on more than printer resolution. Module size, contrast, data content, surface quality and scanning conditions affect readability. Print and scan a representative sample before production use.

Substrate and ink compatibility

General descriptions such as “plastic”, “carton” or “metal” are not enough to guarantee a result. Materials that look similar may have different coatings, oils, moisture or surface energy. Water-based ink is commonly evaluated for porous materials, while solvent-based ink may be evaluated for selected non-porous materials. Compatibility, drying time and durability must still be tested on the actual sample.

PTS does not assume that one test result applies to every material supplier or production batch. Retesting may be necessary when the material, coating or process changes.

Six checks before purchase

1. Clarity: Is the text, barcode or QR code readable at the intended size?
2. Adhesion: Is the result acceptable after the agreed drying time and handling test?
3. Position: Can the operator or conveyor place the code consistently?
4. Speed: Can the complete workflow meet the required output?
5. Environment: Do temperature, humidity, dust or a wet surface affect the result?
6. Operation: Who will prepare messages, inspect prints and care for cartridges?

Is TIJ maintenance-free?

No. TIJ systems generally have simpler maintenance routines than some other coding technologies, but they still require correct cartridge care, nozzle cleaning according to instructions, suitable storage, alignment and accessory checks. The actual routine depends on the printer, ink and operating environment.

Frequently asked questions

Can one printer work on every surface?

This should not be assumed. Ink selection and print performance depend on the material, coating, surface cleanliness and operating conditions. Provide the actual sample for testing.

Does 600 dpi guarantee a scannable QR code?

No. Resolution is only one factor. Code size, contrast, data, surface, printing distance and the scanner must also be tested.

How quickly will the ink dry?

There is no single drying time for every substrate. Establish it through a sample test under the expected operating conditions.

What should I send to PTS for evaluation?

Prepare the actual product or packaging, intended message, print size and location, quantity, speed, environmental conditions and how the item will be handled after printing.

Conclusion

There is no single best printer for every factory. A suitable choice comes from matching the code, substrate, ink, print size and operating workflow. Contact PTS Technology or WhatsApp +6014-360 0265 to discuss a demonstration and sample-print evaluation before deciding.
