All labels are US-made and backed by our 100% satisfaction guarantee.

Frequently Asked Questions

What printers use a 1" core direct thermal label?

Compact desktop thermal printers typically use 1" core rolls. Common models include the Zebra GK420d, ZD220, ZD230, ZD410, and LP2824; Dymo LabelWriter 450 and 550 series; Honeywell PC42t and PC23d; TSC TE210 and TE310; and Bixolon SLP-TX403. Check your printer's media specification for the required core size before ordering — industrial-class printers generally require 3" core rolls.

Are 1" core direct thermal labels the same as Dymo-compatible labels?

Yes — Dymo LabelWriter printers use a 1" core, so all labels in our 1" core direct thermal collection are compatible with Dymo printers when the dimensions match. We also carry a dedicated Dymo Compatible Labels collection that lists labels by Dymo model number for easy cross-reference.
