Abstract
A printer includes identification circuitry disposed in a print head for identifying the type of the print head loaded on a carriage portion for printing characters on a print paper, and head connectors disposed on the carriage portion for enabling a plurality of different types of print heads to be commonly connected with a drive circuit and a control portion. The control portion is operative to identify the type of the loaded print head on the basis of the content of the identification circuitry, and also to perform controlling of the drive circuit under certain controlling conditions corresponding to the type of thus identified print head.
