I purchased this from Amazon for 140,000 yen, but I no longer need it, so I am selling it. Please refer to the following details: This is a handheld marking machine (inkjet). The following content is quoted from the Amazon page: Completely portable high-resolution inkjet printer: Can print on anything using various absorbent materials such as wood, cardboard, and cloth. The B30 series only works with water-based ink cartridges - Model: EB21B (Default model black EB21B is included in the package). Supports multi-printing: Text, time, numbers, QR codes, symbols, images, and logos. Supports import and export functions from a database and can print assigned codes (variable two-dimensional codes, barcodes, and text). Maximum print height: 1 inch / 25mm. Supports multi-line printing with adjustable print height. Design with a free layout; you can adjust the font and size of the characters. Easy operation: Place the roller of this handheld inkjet printer on the surface to be printed and press the print button. Then, start moving the printer across the surface, and inkjet printing will be done automatically. This printer adapts to the user's speed and produces the same imprint with fast or slow movements. (The included guide plate is properly positioned when printing on small bottles and containers.) Includes instruction manual.
