Key Takeaways

  • How many labels fit on one A4 at 40×30 mm: 36 (4×9) with default margins — set quantity to 36 for one page
  • Why print Actual size: Fit to page shrinks the sheet so stickers are the wrong physical size and may fail scans

Goal

Print a full A4 of unique inventory barcodes without desktop label software.

Steps

  1. Open Barcode Label Sheet.
  2. Set Prefix (short is better on small stickers — e.g. TT).
  3. Set Quantity to 36 and Random length to 10 for one full page at 40×30 mm.
  4. Keep Digits, Show code under barcode, and Cut guides on.
  5. Click Generate codes, preview the first Code 128, then Download A4 PDF.
  6. Print at Actual size / 100%. Cut on the guides.
