Barcode Label Generator

Print at Actual size (100%). Never use “Fit” or “Shrink to page”.

In the printer driver, set the paper size to 40 × 30 mm and the gap between labels (usually 2–3 mm).

Run the printer’s media calibration after loading a new roll.

Set the resolution under Label & printer to match your printer, so bars line up with the print dots.

Scan a test label with your own scanner before printing a big batch.
