The Brother DK-11204 17x54mm White Thermal Label (400 units) (QL500/550/570/580) is part of Brother's DK range of pre-cut labels, sold in rolls and made of direct thermal paper, eliminating the need for ink cartridges, toner, or ribbon, as the image is printed by the heat of the label printer itself. The printer automatically detects the length of each label using a chip embedded in the roll, cutting precisely between each one without wasting paper. The back is self-adhesive, ready to stick onto boxes, envelopes, folders, or products, and the printing surface maintains good legibility of the printed text and barcodes. Measuring 17x54mm and with 400 labels per roll, it is a small, multi-purpose format compatible with the QL-500, QL-550, QL-570, and QL-580 printers. It is suitable for labeling CDs, bottles, small boxes, or items where a larger label will not fit.
