ABSTRACT:
A printer driving circuit for a printer having a printer head which is mounted to scan perpendicularly to a direction in which a sheet to be printed upon is fed, the printer head including a plurality of dot printing units arranged on the head so that the units are spaced from one another by respective separation distances in the direction of head scanning, the printer driving circuit includes: a detector for detecting the position of the head; a picture memory for storing print data associated with at least one scan by the printer head at addresses corresponding to printed pixel locations on the sheet; a position generator coupled with the detector for generating information related to respective positions of the printing units on the sheet; a read out device coupled with the detector for reading out the pixel data stored in the picture memory at addresses corresponding to the positions of the printing units relative to the sheet; a timing generator coupled with the position generator for generating a plurality of printing timing signals and having a timing selector to select one of the printing timing signals in accordance with the information related to the respective positions of the printing units, and a driving device coupled with the read out device and the timing generator for driving the printing units according to the pixel data read out by the read out device in response to the input of the selected timing signal.
