Serial printer control system

摘要

A serial printer control system with printing head position control for outputting signals to feed paper and to move a printing head in a direction perpendicular to the paper feed direction for controlling coordinates of the printing head relative to the paper. The system includes cursor keys for outputting a signal to the head position control to move the printing head and to feed the paper set to the printer. There is print control for controlling the printing head while printing on the paper. A print format control data storage stores a position of the printing head and a feed quantity of the paper in sequential order, each time the printing head moves to a desired print position, by driving the position control according to the cursor key operation. The system receives print data composed of plural unit print data. This data is printed at each position stored in the print format control data storage and is sent from a host computer. Also, the system receives print format control data stored in the print format storage, and outputs sequentially the print format control data to the printing head position control upon printing of the unit print data. This in turn drives the printing head position control to sequentially move the printing head to the printing position stored in the print format control data storage, and outputs the unit print data for driving the print control to sequentially print the unit print data.
