The Dymo D1 tape, reference 45803, in 19mm x 7m format, black on white, is the original tape in the D1 range, compatible with Dymo LabelManager electronic label makers and other models that use this tape system. This is the widest format in the D1 range on this list, suitable for labels with more text or for more visible identification from a distance. The black text on a white background ensures good contrast and legibility on labels identifying cables, files, shelves, or office supplies. It is a suitable option for those who already use a Dymo D1 label maker and need to replace the original tape with a guarantee of full compatibility with the equipment.
