Honeywell 225-781-001 - Ribbon Adapter for Intermec PC43t Barcode Printer
This ribbon adapter allows you to use thermal transfer ribbons with 1" cores. Otherwise, the standard core size supported by the Intermec PC43t desktop thermal transfer printer is 1/2" cores.
The 1 inch core based ribbons are also longer, 984 feet, therefore requiring fewer ribbon changes. The 1/2" core ribbons are generally 245 feet long.
