Print oversized thermal-transfer labels in a 6 x 17.5 in format with custom PolyO media configured for applications that need a large printable label area. The roll contains 258 labels and uses a 3 in core, giving teams defined media dimensions and roll quantity when preparing printer media settings and replenishment requirements. Standard perforations separate each label from the next after printing. Zebra Technologies 10046584 is thermal-transfer label media rather than a direct-thermal label roll. Thermal-transfer printing uses a ribbon-based print process, making printer, ribbon, media-width, sensor, and roll-diameter settings important checks before loading the roll. The specified PolyO stock distinguishes this construction from paper label media and should be matched to the material requirement of the finished application. The 6 x 17.5 in label format is the primary differentiator for this custom roll. It provides a long, wide face for applications that require more print area than standard small-format labels, while the perforated construction supports separating labels individually. The 4000T designation is retained as part of the supplied media description, alongside the custom size, PolyO stock, thermal-transfer format, 3 in core, and 258-label roll quantity.
