Abstract

Abstract A printing apparatus system includes a plurality of type units each having a plurality of type elements and each being different from the others. Each type unit may be mounted in the apparatus. A detector detects which of the type units is so mounted and produces a detection signal representative thereof. The printing pressure with which each type element is imprinted on a print medium is determined in accordance with the particular type wheel mounted in the apparatus as indicated by the detection signal. Additionally, the amount of advance of an ink ribbon for imprinting a type element on a type unit is determined in accordance with the particular type unit mounted in the apparatus, again as indicated by the detection signal.
