Zebra labels are genuine Zebra-brand thermal labels for Zebra desktop, industrial and mobile label printers, from 2 x 1 in product labels to 4 x 6 in shipping labels.
The letter in each grade name sets the print method: D = direct thermal (no ribbon) and T = thermal transfer (ribbon required), so a ZD421d takes D labels and a ZD421t takes either. Core size typically follows printer class: 0.75 in for mobile, 1 in for desktop models like the ZD421 and ZD411 (successor to the ZD410), and 3 in for industrial models like the ZT411.
