Maintain an established custom label format with Zebra Technologies 10046578, a roll of 3 x 5 in PolyO label media. The roll is marked with a 3000T designation and 1C configuration, giving teams defined media attributes to match when replenishing an existing label application. Each roll contains 455 labels. The 3 x 5 in format is the primary physical attribute for matching label layout, print placement and application space. PolyO identifies the media construction specified for this roll, while 3000T and 1C are part of the defined custom configuration. These details differentiate this media from generic labels that share only the same nominal dimensions. Use the complete format designation when matching replacement media: custom, 3 x 5 in, PolyO, 3000T, 1C and 455 labels per roll. Retaining all six attributes helps preserve the intended label format where media dimensions and custom configuration matter. This roll is supplied as label print media rather than a printer, ribbon or hardware accessory.
