Abstract
There is provided a printing apparatus which drives a printing wheel in response to a rotation angle data corresponding to an input character code and drives a printing hammer with an impact force corresponding to this input character code. A data processing circuit reads out the rotation angle data from a first memory, supplies a drive data corresponding to this rotation angle data to wheel driving circuit through a first data bus, and reads out the impact force data from a second memory and supplies it to a hammer driving circuit through a second data bus. The information relating to a character is accessed from the first and second memories via the same address.
