About Ecotherm Labels for Brother Printers

Our direct thermal labels are manufactured to standard thermal printer specifications — coated thermal paper, permanent rubber-based adhesive, perforated for easy separation, and wound on standard 1" or 0.75" cores. They work seamlessly with Brother's auto-calibration and are compatible with both Brother's P-touch Editor software and standard label printing applications.

We do not sell ribbons or thermal transfer labels. All Ecotherm products are direct thermal — no ribbon required, ideal for shipping labels, address labels, and short-to-medium-term labeling applications (typically 6-12 months of image life under normal storage conditions).

A Note on Brother DK Die-Cut Labels

Brother sells branded "DK" pre-die-cut labels (DK-1201, DK-1202, etc.) that come in fixed sizes for QL-series printers. Ecotherm does not currently offer Brother-branded DK labels. Our continuous direct thermal labels work with Brother QL printers when configured for continuous media mode, but if you specifically need DK pre-die-cut labels, you'll want to purchase those directly from Brother or an authorized DK reseller.
