Printing apparatus and method of controlling it

摘要

Disclosed is a printer (1) in which nozzles for printing dots are positioned in a zigzag arrangement and which has a simple circuit for sending to these nozzles printing data that have been expanded into a bit-map image. When sending data to a print head (5) in which odd-numbered nozzles (11) and even-numbered nozzles (12) are alternately positioned, bit data n + s and the bit data n from an image buffer (20) that correspond to respective nozzles 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. <IMAGE>
