Product name The name from the catalogue, e.g. “A4 Offset Paper”. Variant name Joined to the name with a dash, e.g. “Matador Exercise Book 100 Pages - 70 GSM”. Products with no variant simply lose the dash. Barcode (the bars) Leave this on. Without the bars the counter scanner cannot read the sticker — it becomes a price tag only. Barcode number The digits under the bars, so the code can still be typed in by hand if the scanner will not read it. Unit Pcs, Ream, Dozen — whatever the product is counted in. It goes last, after the slash: “Matador Exercise Book 100 Pages / pcs”, or “… / ৳55 pcs” when the price is on too. Price Goes after the slash, before the unit: “… / ৳315 Ream”. Careful: change the price later and every sticker already on the shelf is wrong — you have to print those products again. Paper A4 sheet of stickers Roll — label printer (Rongta RP400 etc.) A roll printer pulls one sticker at a time, so the page IS the sticker. Margins, rows and gap-down are switched off — the printer’s own gap sensor finds each label. Label width (mm) One sticker, its left edge to its right edge. Not the paper — the sticker. Label height (mm) One sticker, its top edge to its bottom edge. Labels across How many stickers sit side by side in one row. Count them on the sheet. Labels down How many rows there are from the top of the sheet to the bottom. Left margin (mm) From the left edge of the sheet to where the first sticker starts. Top margin (mm) From the top edge of the sheet down to where the first row starts. Gap across (mm) The blank strip between two stickers standing side by side. Often 0 — most sheets have them touching. Gap down (mm) The blank strip between one row and the row under it. Often 0.
