OPERATING DEVICE AND OPERATING METHOD OF PRINTER

摘要

An operating device of a printer in which printing can be performed using a processless plate in order to suppress an increase in preparation time of the printer and an increase in loss paper incident thereto by performing water treatment of the processless plate easily and appropriately thereby lessening burden on an operator; and an operating method of a printer. The operating device comprises a printing block judging means for judging whether a printing block attached to the plate cylinders (31b-34b) of a print unit section by plate change is a processless plate or not, and a control means (9) for rotating the plate cylinders (31b-34b) at a preset speed under an off-state of not touching a print sheet when the printing block judging means judges that the printing block is a processless plate at plate changing, and controlling to perform water treatment for a preset time.
