Abstract

A data generation logic for a dot matrix printer is provided that works independently from the printer controller and simplifies dot image handling. It is suitable for those printers which have complicated pin alignment, such as the multi-column line printer or diamond shaped alignment serial printer. To pick up a desired data bit from the line image buffer, this logic uses a memory circuit as an address translator for image buffer to be addressed with respect to the head carrier position and dot pin number. This logic is applicable to any type of dot pin alignment with some minor modification of circuit and initialization of memory contents.
