Barcode Label Sheets
Place barcodes on sticker sheets and print them, or save the result as a PDF. Pick the layout that matches your sheet, paste your codes, and every code lands on its own label. Make the codes first with a generator such as sequential numbers, Code 128 or QR codes — each of them has a "Put on label sheets" button.
Printing tip: in the print dialog set scale to 100% (not "fit to page") and margins to none, otherwise the barcodes will not line up with the stickers. Test on plain paper first.
