PURPOSE:To exert no influence on the medium of a recording source when a recording medium is short by corresponding automatically to the shortage of the recording medium being in the course of recording both sides and recording so as to be related to a prescribed page. CONSTITUTION:When there is no number of sheets of a feed paper part of a printing device 3-6, and it is detected that there is no paper in some even page, idle printing of its even page is executed. At the same time, in accordance with a detecting signal, a CPU3-3 releases a printing register 3-9 of an odd page corresponding to its page, and in the timing of the time of printing its odd page, idle printing is executed, and actual printing is not executed. Subsequently, the register 3-9 corresponding to the odd page which is not printed due to no-paper is checked by the CPU3-3, the register 3-9 corresponding to the page which is not printed due to no-pager is released, printing to the remaining odd pages is executed until a value of a printing counter 3-15 goes to ''0'', and an automatic counter-measure is executed so that such the influence as double recording, unrecording, etc. is not exerted on a recorded medium. |
