PURPOSE:To enable a continuous printing without degrading a printing quality, by a method wherein a voltage of a battery is detected during the paper feed in an automatic paper feeder, and a printing processing is interrupted if a voltage of not more than an allowable value is detected. CONSTITUTION:In a continuous printing using an automatic paper feeder 31, a voltage of a battery is checked first, and whether it is not more than an allowable value is judged. In this case, if, during the voltage check, a voltage of not more than the allowable value is identified once, a succeeding printing process is not conducted. On the other hand, during the voltage check, a voltage of not more than the allowable value is not identified, a sheet of paper is fed to a printer 23 using the automatic paper feeder 31. At this time, if the paper is not fed normally, the printing processing is stopped. Thereafter, a printing is carried out by every line by the number of lines for one page. At this time, if one-line printing is not carried out normally, the printing processing is stopped. Then, at the completion of a printing for one page, the printed paper is discharged to a stacker of the automatic paper feeder 31. |
