ABSTRACT:
A printing apparatus is capable of freely selecting a plurality of sheet feeding units each having a different controlling method. It is discriminated as to which one among plural kinds of sheet feeding units is fitted, and printing and a motor for a sheet feeding-unit are controlled based on the result of the discrimination from an output from a sensor disposed on the sheet feeding unit. Especially, in the case that a roll shaped paper feeding unit is fitted, it is judged that a printing medium reaches the position where printing can be started when a TOF sensor detects black color, and in the case that a cut sheet feeding unit is fitted, it is judged that the recording medium reaches the position where printing can be started when the TOF sensor detects white color.
