is an output changeover switch, 7A and 7B are computers, 8 is a computer changeover, and 9 is a printer. Note that the same reference numerals in each figure indicate the same or equivalent parts.

Claims (1)

[Scope of utility model registration request] Input the print data from the computer,
It also identifies a buffer section that outputs print data while accumulating it, and the printer format data in the print data stored in this buffer section, stores the printer format data, and then outputs the print data at intervals of a predetermined time or longer. When outputting the print data, the printer format control section outputs the previously stored printer format data to the printer prior to outputting the print data, and the buffer section is switched and controlled by the control signal of the printer format control section. A printer buffer comprising an output changeover switch for connecting one of the output ends of the printer format control section.
