Label and QR Code Printer for Sticker Sheets

Label and QR Code Printer for Sticker Sheets is an offline app (one HTML file in a zip) that lays labels out on the sticker sheets you already buy. You describe a label once, with text lines and a QR code or a barcode, fill it from a list or a number range, and print it or save a PDF whose labels sit on the die cuts.

The problem it removes: Shelves, bins, cartons and equipment are labelled by hand, or in a word processor where the grid drifts, numbers repeat and the code is pasted in as a picture. Every sheet size needs its own template, and a small shift in the printer ruins a sheet of expensive stickers. This app keeps the sheet sizes, the label designs and the numbering in one place, with a test page to line the printer up first.

What is inside:

• Label designer: up to four text lines with merge fields, a QR code, Code 128 or EAN-13, placed left, right, top or bottom, with a border and padding
• Eight common A4 sticker sheet grids you can edit, with a check that the grid fits the paper
• Batch list with copies per item, batch names, and CSV import and export
• Serial number ranges with a prefix, padding, step and suffix
• Test page with a 100 mm ruler and offset buttons in 0.1 mm steps to line the print up with your stickers
• Start at any label position to reuse a part-used sheet, and an outline mode for trials on plain paper
• Print through the browser or download a PDF at exact page size
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: warehouse and shop staff, facilities teams, small makers and offices that label bins, cartons, products and equipment and want a QR code or a barcode on each label without a design tool.

What it is NOT: It does not register barcodes: an EAN-13 number is the one you type and the app does not check that it was allocated to you. It does not scan or read codes, has no photo or logo layout, and does not connect to a printer or a stock system. The sheet grids are common sizes, not a promise that any maker's sheet matches. The PDF file holds Latin letters only: Arabic text prints through the browser's own Print and Save as PDF. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Your data stays on this device in your browser. Back it up with Export; clearing browser data loses it otherwise.

Verified by us: scripted tests in Chromium (129 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and an independent recalculation by a separately written Python evaluator of 668 calculated values (25 randomised rows plus the example data) with 0 mismatches. Safari engine (WebKit): smoke test passed; Firefox: could not be launched. Not tested: Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
