PURPOSE:To contrive reduction in time loss in printing, by causing a controlling part to effect printing after paper jam, starting from the first printing data for the page having been printed when the paper jam has occurred, based on a stored printing condition and a paper jam detection signal from a sensor. CONSTITUTION:When transmission data is present in a host device 2, data transmission to a printer 1 is conducted, and printing data is stored into a data memory 1b. When it is found that paper jam is absent upon detection by a sensor part 1f, an instruction for printing is outputted, and printing is conducted sequentially on the first, second and latter pages of a continuous form paper 5. When paper jam is detected during printing on the third page, a detection signal is sent to a controlling part 1a, the occurrence of paper jam is reported to the host device 2, and transmission of the printing data is stopped. The end of the printing data and the time of occurrence of the paper jam are stored. After disposing of the jam and resetting a paper, the operator depresses a preparation completion key to send a recovery signal to the controlling key 1a, upon which the first printing data for the page relevant to the occurrence of the paper jam is immediately detected, and the third page is printed starting from the head. Thus, the loss of time in printing after disposal of paper jam can be minimized. |
