Before driving the PF motor in accordance with the control from (1), the drive amount is set to (A) (301), the drive amount is set as a counter, and the determination as to whether there was no paper last time is made by checking the paper out flag ( 302). The paper out flag is set when the PE state is detected by the PD and is within a predetermined amount, and is reset when printing is impossible outside the predetermined amount even in the paper presence state or the paper absence state.

9、310）。If the paper absence flag is reset, that is, if printing is possible with paper last time, the counter A is decremented for each paper feed unit (303) and paper presence detection is performed (304).
If there is paper, follow this loop until A = 0. When the absence of paper is detected, the remaining printable paper feed amount is set to (L) (305). At the same time, a paper-out flag is set (306). After this or in the case where the paper absence flag is set, that is, in the case of the previous PE state, the values of the counters A and L are lost for each paper feed unit without performing paper detection (307, 308). When the value of the counter L becomes 0, printing is disabled and the paper out flag is reset (30
9, 310).
