WITH A MEMORY DEVICE EQUIPPED LABEL-SPOOL FOR A HANDHELD LABELLER

摘要

A handheld label printer (10) receives spools (20) containing print media (2 2) of different sizes and types. Each spool (20) contains a memory chip (30) which stores information about its print media, and this information is conveyed to the printer through concentric electrical contacts (32, 34) on the end of the spool. The concentric electrical contacts engage stationary contacts on the printer (36, 38), and this electrical connection is insensitive to incidental rotation of the spool when it is inserted into the printer and used.
