Abstract

PURPOSE: To make it possible to perform print operation in a minimum switching time, by comparing currently stored character size with character size assigned next and by changing feed pitches of a head when the both disagree.
CONSTITUTION: A character bit pattern sent from word processor WP to printer control part PC has a bit for assigning character size and control part PC exercises a supervision over the bit invariably. Then, the previous character size is stored and compared to the current character size command and when the both disagree mutually, clutches CL1 and CL2 are changed over to change feed pitches of print head TM. Thus, the lowering of the print speed due to the operation time of clutches is prevented as much as possible, so that high-speed print operatation can be performed in the minimum switching time.
