Dymo 45017 D1 LabelMaker Compatible Tape 12mm x 7m Black on Red S0720570

It’s a Dymo 45017 D1 label cassette that prints black text on red tape, sold under part number S0720570/45017. The roll is 12 mm (½") wide and about 7 m (≈23 ft) long — handy when you want attention-grabbing red labels.

Red labels are excellent for warnings, “Do Not Remove” tags, priority filing, or any label that needs to stand out at a glance. If you want something that screams “look here” — red with black print is the classic choice.

The 45017 is a D1-format cassette and works in DYMO LabelManager and many LabelPoint devices that accept D1 tapes. If your label maker says it uses “D1” cassettes, this roll will almost certainly fit.

Depending on the listing, Dymo 45017 is available both as a standard D1 and, in some instances, as a high-performance polyester version. Generally, it is fairly durable, resists everyday wear, and features an easy-peel backing that facilitates neat application. For long-term outdoor exposure or extreme abrasion, polyester “high-performance” D1 tapes are recommended; please test one label first if you are uncertain.

Snap the D1 cassette into your label maker until it clicks, close the cover, choose 12 mm width if needed, then print. If text is faint: reseat the cassette, clean the print head (soft, dry cloth), make sure the label path is free of dust, and try a fresh cartridge — most feed/print quirks are solved by reseating or cleaning.

You’ll find genuine 45017 at major retailers and office suppliers (DYMO, CDW, Walmart, and authorized resellers). Compatible third-party D1 tapes exist and can be cheaper — they often work fine, but buy from reputable sellers (Megalabels, 3ReeLabels) with returns and favorable reviews if you want peace of mind. Price varies by store and pack size; single cartridges typically sit in the office-supplies price band, while multipacks lower the per-roll cost.
