ABSTRACT:
A pattern pitch adjustment is applied to dot matrix pattern data as it is output from a CPU to a printer. The data is transferred from a DMA to the printer bit by bit, and the number of synchronizing signals output from the printer for each bit is counted to decide picture element timing. During a given period of time after transferring each data pattern, a waiting signal is applied to the DMA so that space picture element data is fed to the printer.
