A hand held label printer receives spools containing print media of different sizes and types. Each spool contains a memory chip which stores information about its print media, and this information is conveyed to the printer through concentric electrical contacts on the end of the spool. The concentric electrical contacts engage stationary contacts on the printer, and this electrical connection is insensitive to incidental rotation of the spool when it is inserted into the printer and used.
