Abstract
A printer, in which nozzles for printing dots are positioned in a zigzag formation, has a simple circuit for sending to these nozzles printing data that has been expanded into a bit-map image. When sending data to a print head in which odd-numbered nozzles and even-numbered nozzles are alternately positioned, the bit data of string n+l and the bit data of string n that correspond to respective nozzles inside image buffer 20 are converted from parallel to serial before being sent. Odd-numbered bit data and even-numbered bit data are then selected from the bit data using divided clock signals, and are converted from serial to parallel for printing.
