Zebra ZD621D and Linerless Labels: Which Roll to Choose?

The Zebra ZD621D is Zebra's top-of-the-line desktop printer. Like all thermal printers designed for linerless labels, it performs very well, provided it is fed with the corresponding linerless label roll in terms of width, diameter, and adhesive. Its strength lies in the combination of speed and capacity: large formats, large roll diameters, and high throughput in a compact case. Here is what it accepts and how to choose the right consumable. Subject to manufacturer eligibility.

What the Zebra ZD621D accepts

On the hardware side, it covers a width range from 40 to 108 mm, enough to serve both small price tags and wide order formats. The roll can reach an outer diameter of 127 mm, and this diameter directly affects autonomy: the larger it is, the more linear meters the roll offers and the less frequent the reloads. The cores supported on compatible references are 12.5, 19, 25, 25.4, and 40 mm. Subject to manufacturer eligibility.

The labels that go with it

In practice, it is fed with rolls of 40, 58, 80, and 100 mm wide, up to 127 mm outer diameter. The width is chosen according to the use, then the largest allowable diameter is selected to space out reloads. These two criteria, usable width and maximum diameter, are enough to guide the choice.

The question of adhesive

The adhesive determines the label’s hold and the cleanliness of the surface once removed. On this model, several types coexist. There is permanent adhesive, which ensures long-lasting hold on most surfaces for logistics and long-term labeling; reinforced adhesive, which maintains grip on difficult surfaces, in cold or humidity; and repositionable adhesive, which peels off and repositions cleanly, ideal for order labeling and surfaces to be preserved. The choice depends on the targeted surface and the expected label lifespan. Subject to manufacturer eligibility.

Check compatibility

Before ordering, the safest approach is to compare your exact model with the list of validated linerless rolls.
