Thermal transfer labels on a 1" core from LabelsOnline.com are designed for compact desktop thermal transfer printers that accept small-core media — including select Zebra GK420t, ZD220-tt, ZD230-tt, and other tabletop thermal transfer models. While most thermal transfer printing is done on 3" core rolls, certain entry-level and compact thermal transfer printers require 1" core rolls, and this collection covers those configurations.

Available in premium paper for standard barcode and product ID applications, and white polyester for durable labeling applications requiring moisture, chemical, or abrasion resistance. Sold in carton quantities. All labels are US-made and backed by our 100% satisfaction guarantee.

Frequently Asked Questions

How do I know if my thermal transfer printer uses a 1" core?

Check your printer’s media specification or look at an existing roll — measure the hollow center tube diameter. A 1" core is approximately 1" in inner diameter. Most desktop thermal transfer printers use a 3" core; 1" core thermal transfer rolls are used by a smaller subset of compact models. If your printer’s spec sheet lists media core as "1 inch" or "25.4mm", this collection is the right one.
