Abstract
A ribbon assembly having a ribbon supply spool and a ribbon take-up spool. Attached to either the ribbon supply spool or the ribbon take-up spool is a bar code. The bar code is machine readable and is encoded with data relevant to the operation of printing means suitable to employ the ribbon assembly. The printing means comprises reading means for reading the bar code present on the ribbon assembly. Based on the information encoded on the bar code and read by the reading means, the operating parameters of the printing means are adjusted for the specific ribbon assembly employed.
