The B71S and B71XS additionally feature a built‑in scanning module, enabling scan‑to‑print functionality, along with a multilingual UI and database integration—delivering fast and accurate traceability and identification.

Streamline your warehouse operations with the Bentsai B71S Series. Unlike standard handheld printers, these models feature a Built-in Barcode Scanner. Simply scan an existing barcode, and the printer will instantly clone it or retrieve associated data from your database to print immediately. The integrated scanner enables instant 'Scan-to-Print' capability, allowing you to clone existing barcodes or restore damaged labels without manual typing errors.

Why Choose Bentsai B71/B71X?

  • Prints on Anything: Waterproof solvent ink prints permanently on Plastic Bottles, Glass Jars, Metal Cans, and Cardboard Boxes.

  • Perfect for Curved Surfaces: The unique "Stamp" design allows you to print on the bottom of concave cans or bottle caps where other large printers cannot reach.

Frequently Asked Questions for Bentsai B71 Series Handheld Inkjet Stamp Printer | 12.7mm & 25.4mm (1 Inch) - Print Bigger Logos & QR Codes on Boxes

What is the difference between the Bentsai B71S and B71XS handheld inkjet printers sold in Malaysia?
Both models are sold exclusively through PTS Technology Sdn Bhd in Malaysia and both include a built-in scanning module for scan-to-print functionality. The key difference is print height. The B71S uses a 0.5-inch printhead with a maximum print height of 12.7mm, supporting up to 5 lines of text, making it suitable for smaller markings such as batch codes and expiry dates on carton boxes. The B71XS uses a 1-inch printhead with a maximum print height of 25.4mm, supporting up to 10 lines of text, and is better suited for larger format printing including 2-inch pallet QR codes and multi-line product information on industrial packaging.
PTS Technology Sdn Bhd is the exclusive authorized distributor for Bentsai handheld inkjet printers in Malaysia. Buying through PTS Technology guarantees genuine products, valid local warranty coverage, local technical support, and access to original ink cartridges and spare parts. For enquiries, visit ptstsb.com.
The ink type determines the printable surface. Water-based ink cartridges are designed for porous and semi-porous surfaces such as corrugated carton boxes, kraft paper, wood, fiberboard, and textile materials. Solvent-based ink cartridges are designed for non-porous surfaces such as plastic packaging, glass bottles, metal plates, aluminium foil, laminated cartons, and cables. Both ink types are available locally through PTS Technology for both the B71S and B71XS models.
Yes. Both the B71S and B71XS have built-in software that supports fully automatic date stamping, expiry date calculation, and batch counter sequencing. Production dates, manufacturing dates, expiry dates, shift codes, and sequential lot numbers can all be configured to update automatically with each print cycle, eliminating manual input and reducing labelling errors on the production line.
Yes. Both the B71S and B71XS support high-resolution printing of multiple barcode formats including Code 128, Code 39, EAN-8, EAN-13, UPC-A, UPC-E, and ITF-14, as well as 2D code formats including QR Code, Data Matrix, and GS1 Data Matrix. The B71XS additionally supports printing of large 2-inch pallet QR codes using a dedicated fixture for EPAL pallet identification. Variable barcodes linked to a database can also be printed sequentially via USB import.
Both the B71S and B71XS are equipped with a built-in scanning module that allows operators to scan an existing barcode or QR code directly from a product or packaging, then immediately reprint it without manual data entry. This is particularly useful for relabelling, pallet code restoration, and reducing data entry errors in warehouse and logistics operations. To use this function, tap Edit, then Add, then Scan, align the scanner with the code, and press the Print button.
The solvent-based ink used with the B71XS is formulated for fast adhesion on non-porous surfaces such as plastic, glass, metal, and aluminium foil. Drying time is typically within 1 to 3 seconds under standard production conditions, making the B71XS suitable for high-speed manufacturing and continuous packaging lines where ink smearing must be avoided.
Yes. The B71S with water-based ink cartridge is specifically optimized for porous surfaces including corrugated carton boxes, kraft paper bags, uncoated wood, and fiberboard. It prints clearly and consistently on these materials with fast ink absorption, making it a practical solution for carton coding, warehouse labelling, and outbound shipment marking in Malaysian manufacturing and logistics facilities.
Yes. Custom logos and company graphics in JPG, JPEG, PNG, or BMP format can be imported into the device via a USB flash drive. Before importing, ensure the image vertical pixel count does not exceed 150 pixels. Copy the image file into the pictures folder on the USB drive, insert the drive into the printer, and import via the U-Disk menu. Once imported, logos can be combined with text, barcodes, dates, and counters in a single print template.
No. Both the B71S and B71XS are fully standalone units that operate without any external PC, laptop, or proprietary software. All print template creation, editing, counter setup, date configuration, and file management are performed directly on the built-in 4.3-inch HD capacitive touchscreen. The device runs on a Linux-based operating system and supports more than 20 system interface languages.
Yes. Variable data files prepared in Microsoft Excel or WPS Spreadsheet can be exported as TXT or CSV format and imported into the printer via a USB flash drive. The device supports sequential printing of variable text, variable QR codes, and variable barcodes, with up to three data columns supported per import file. This is suitable for printing unique serial numbers, customer order references, product codes, or personalized packaging labels in sequence.
The B71S supports barcode formats including Code 128, Code 39, EAN-8, EAN-13, UPC-A, UPC-E, and ITF-14, which covers the most commonly required formats for retail, FMCG, and supply chain compliance in Malaysia. For 2D codes, it supports QR Code, Data Matrix, and GS1 Data Matrix. The B71XS additionally supports large 2-inch GS1 QR code printing for pallet identification, which is useful for manufacturers supplying to major retailers or export markets.
The B71S supports up to 5 lines of text per pass with a minimum character height of 0.8mm and a maximum print height of 12.7mm. The B71XS supports up to 10 lines of text per pass with a minimum character height of 1.6mm and a maximum print height of 25.4mm. Both models support a maximum print length of 85mm per pass at print speeds of up to 100mm per second.
The built-in 3200mAh rechargeable battery supports up to 8 hours of continuous printing, which is sufficient to cover a full standard manufacturing shift without needing to recharge. The device can also operate simultaneously on external power using the included DC 9V 2A power adapter, allowing uninterrupted use during long production runs.
Water-based ink cartridges for the B71S & B71SX are available in black, cyan, magenta, yellow, and green. Solvent-based ink cartridges for the B71S & B71XS are available in black, cyan, magenta, yellow, white, green, and invisible security ink. PTS Technology maintains local stock of the most commonly requested colors for immediate dispatch to minimize production downtime.
The B71S supports both 300 DPI and 600 DPI resolution, giving users the flexibility to choose between faster output at 300 DPI or sharper detail at 600 DPI depending on the application. The B71XS supports 300 DPI resolution. Both models offer five levels of grayscale adjustment, with Level 3 as the default, allowing operators to control ink density and optimize print quality for different surfaces and materials.
If print output shows white lines, faded areas, or missing characters, first run the automatic nozzle cleaning function by tapping Maintenance then Nozzle Cleaning on the main screen. The system will automatically eject a small amount of ink to clear the nozzle. If the issue persists, manually clean the nozzle using a lint-free cloth by wiping in a single direction from top to bottom only. For water-based cartridges, use a dry cloth or one lightly moistened with distilled or deionized water. For solvent-based cartridges, use a cloth moistened with high-concentration alcohol or 98% IPA. Never use tissues or fibrous cloths as fiber residue may clog the nozzle permanently.
If the printer will be idle for more than 4 hours, the ink cartridge should be removed and the original protective cartridge clip reattached to prevent the nozzle from drying out. This is especially important in Malaysian factory environments where ambient temperature and humidity can accelerate ink evaporation at the nozzle tip. Proper cartridge storage between shifts will extend cartridge lifespan and maintain consistent print quality.
Each ink cartridge has a capacity of 42ml. Print yield varies depending on character size, content density, resolution setting, and grayscale level. Under standard operating conditions, a single cartridge is capable of producing hundreds of thousands of standard-sized characters. Contact PTS Technology for a yield estimate based on your specific print template and production volume.
Yes. Both models use a non-contact sliding printhead mechanism with an ink throw distance of 2mm to 5mm between the nozzle plate and the print surface. This non-contact printing method allows clear marking on curved, uneven, or irregular surfaces such as bottles, round containers, PVC pipes, and pre-packaged food products without the need for direct surface contact.
Both the B71S and B71XS weigh approximately 950g including the ink cartridge. The device features a built-in carry handle on the top and is designed for stable handheld operation. For extended use on the production floor, the foot switch port also allows hands-free triggering, reducing operator fatigue during high-volume marking sessions.
No. There are no software licensing fees, annual subscriptions, or scheduled maintenance charges. All features including template editing, database printing, counter functions, barcode generation, and firmware upgrades via USB are included at no additional cost. The total operating cost is limited to hardware and ink cartridge replacements only.
Yes. PTS Technology accepts official Purchase Orders from registered business entities in Malaysia. Full B2B procurement workflows are supported, including formal quotation issuance, purchase order processing, delivery order documentation, and SST-compliant tax invoice issuance for accounting and company expense claim purposes.
The B71 Series comes pre-installed with the Yahei font as default and supports both TrueType and dot-matrix font formats. Additional custom fonts in TTF format can be installed by downloading the font file on a PC, copying it into the fonts folder on a USB flash drive, inserting the drive into the printer, and importing via the U-Disk menu. Custom fonts are particularly useful for facilities that require branded label typography or non-Latin character sets.
Yes. The B71XS specifically supports printing of large 50mm by 50mm 2D pallet QR codes for EPAL pallet identification using a dedicated optional fixture for accurate alignment. It also supports scan-to-print pallet code restoration, allowing operators to scan a damaged, faded, or contaminated pallet QR code and instantly reprint a clear replacement for relabelling. This function is only available on the B71XS model and is not supported on the B71S.
Print template files saved on the device can be exported to a USB flash drive via the U-Disk export function and then imported into another unit using the same import procedure. This allows standardized print templates to be duplicated across multiple B71S or B71XS units on different production lines without the need for a PC or network connection, ensuring consistent output across your entire facility.
No. There is no minimum order quantity for replacement ink cartridges. Procurement managers can requisition single cartridges or any quantity according to current inventory needs, with no stockpiling obligations. Both water-based and solvent-based cartridges in all available colors can be ordered individually and are dispatched from local stock.
Purchasing directly through PTS Technology Sdn Bhd, the sole exclusive distributor of Bentsai in Malaysia, guarantees product authenticity. Genuine B71S and B71XS units use smart-chip ink cartridges that the device automatically detects and verifies upon installation. Units purchased through PTS Technology are covered under a locally serviced warranty with all claims, repairs, and technical support handled by the PTS Technology team in Malaysia.
No. The B71S and B71XS are designed exclusively for handheld operation and do not support conveyor belt integration. The foot switch port on the device is intended to allow hands-free print triggering while the operator holds the printer manually against the surface, which is useful for high-volume handheld stamping tasks where the operator needs both hands free. For automated inline conveyor belt printing, PTS Technology recommends the Bentsai industrial inkjet printer range such as the E62P, which is purpose-built for fixed-mount conveyor line integration. Contact PTS Technology for more information on the right solution for your production line requirements.
