Media Core Size

Media supplied for the P4T Se- ries printers will have two pos- sible core sizes, depending on the media type. Journal media and most label media is supplied with a 0.75” [19.1 mm] diameter core to maximize the amount of media contained on a roll.

P4T printer media supports are set at the factory for 0.75” diam- eter media cores.

RP4T printers (equipped with the RFID encoder) are configured for media with 1.38” [35.05 mm] diameter cores since RFID me- dia cannot be wound around a small diameter core without both degrading its ability to feed properly past the printhead and causing possible damage to the embedded RFID circuitry.
