1-Inch Handheld Inkjet Printer 25.4mm Wide Format, Removable Battery

• If your work involves information that needs more vertical space than a 12.7mm printer can give, but you don't want to move up to a heavy dual-head industrial machine, the ZG1691-S is the sweet spot — 1 inch of real print height with zero physical compromise.

Usage Scenarios

Beverage Bottle Multi-Line Batch Coding

• Beverage production lines often require three or more lines of information on curved bottle surfaces — production date, line number, shift code, and expiration date stacked vertically. A 12.7mm printer forces the font size down to fit three lines, making the text difficult to read on retail shelves. The ZG1691-S at 25.4mm accommodates three clear text lines without crowding, and the 2–5mm spray distance handles the curvature of PET bottles, glass bottles, and aluminum cans without requiring a perfectly flat surface.

Medical Device UDI Labeling

• Unique Device Identification mandates require both human-readable text and machine-readable barcodes on medical device packaging. A 1-inch print span allows a GS1-128 barcode and its companion text to sit side by side in a single pass, eliminating the alignment errors that occur when stitching two half-inch scans together on small-label packaging. The removable battery means operators can keep printing through an entire batch sterilization run without stopping to recharge.

Glass and Ceramic Surface Marking

• Glass jars, ceramic tiles, and porcelain products need temporary or permanent identification marks — lot numbers on cosmetic jars, size codes on tile backs, or production dates on glass bottles. The ZG1691-S's quick-dry solvent ink adheres well to smooth non-porous surfaces from 2–5mm distance. The 1-inch print height accommodates a barcode plus text on the narrow bottom rim of a cosmetic jar. Note: marks on glass are removable with alcohol.
