Abstract

PURPOSE:To arbitrarily obtain a layout on the surface of a recording medium without recording unnecessary information on the surface of the recording medium by a method wherein recording medium sensors for detecting the presense or absence of the recording medium on first and second feed paths are provided, and a difference in state between the two recording medium feed paths is clarified. CONSTITUTION:Printing paper 1 is fed from a paper supply device 13 to a first feed path 7 and recorded by a printing head 3 on the surface thereof, thereafter moving to a paper reversing device 15, passes through the surface of a platen 5, and reaches a second feed path 9 to be reversed inside out. After being reversed inside out, the printing paper 1. is recorded with a printing condition set value for a printer on the rear surface thereof as a bar code. Since the printing condition can be recorded on one surface of a recording medium, a layout of characters and graphics can be arbitrarily provided on the other surface of the recording medium. In addition, the set printing condition for the printer can be easily reproduced. Because the outputted data is recorded separately from the printing condition for the printer, there is no possibility that data outputted from an electronic computer and a printing condition for a printer may be recorded on the same surface of a recording medium by mistake.
