Method and circuit for processing dot matrix image data in a page printer

摘要

A method and circuit for processing image data of a dot matrix printer in a page printer. Dot matrix image data is received and how many dots in the page printer correspond to one dot of the image data is calculated. A bit number representative of the location in vertical pins of a dot matrix printer head is initialized to a most significant pin number. A bit corresponding to the bit number of the input data is checked to form a line segment and the line segment is converted into raster data. Further, the raster data inserted in an image buffer, and data of the image buffer is stored in a symbolic buffer. A check is made to see if the bit number of the input data is a least significant pin number. If the bit number of the input data is not the least significant pin number, a next pin number is redesignated.
