ABSTRACT:
Conveying devices, operation of which is stopped during printing, are provided upstream and downstream, as seen in a direction of conveying of a paper, of a platen arranged to face a printing head. The platen is provided with an electrostatic attraction member electrostatically the paper by the application of a voltage. A first control applies the voltage to the member during printing until a leading end of the paper arrives at the downstream conveying device. A second control applied the voltage to the member during printing after conveyance of a trailing end of the paper by the upstream conveying device is completed. Thereby, lifting of the end portions of the paper away from the platen is prevented, thus avoiding unprintable margins at such end portions of the paper.
