Printer settings use 8 / 12 / 24 dots per millimeter. Nominal 203 / 300 / 600 DPI names correspond to effective 203.2 / 304.8 / 609.6 DPI device grids. Screen dimensions use the CSS reference of 96 px/in.

Operating procedure

  1. Enter a GS1 AI string or assemble its fields; enter 17 SSCC digits to calculate the final check digit.

  2. Inspect whole-dot bars, quiet zones and check digit status before printing.

  3. Download a label or switch to Batch CSV / Sequence for thermal rolls and Avery sheets.

Preflight validates supported identifiers and geometry; it does not certify scanner grades. Fix every red error before exporting.
