Abstract: A printer that prints on a rolled recording paper, cuts the printed recording paper to a predetermined length, and ejects the cut recording paper. The printer includes storage 30b that stores a print status wherein, at the time of powering on, the printer references a previous print status based on the print status stored in the storage and, if the previous print operation is not completed, ejects the recording paper for a maximum print length and cuts the ejected recording paper.

Abstract: A cutter unit is incorporated in a printer to cut a paper in accordance with an instruction from a controller of the printer. The cutter unit includes a cutter blade, a position sensor for detecting that the cutter blade is or is not in a reference position, a motor for driving the cutter blade, a drive circuit for the motor, and a cutter control element for controlling the drive circuit on the basis of a result of the detection of the position sensor to operate the cutter blade in accordance with the instruction from the controller.

Abstract: The present invention provides a printer that prints on a rolled recording paper, cuts the printed recording paper to a predetermined length, and ejects the cut recording paper. The printer includes storage means 30b that stores a print status wherein, at power-on time, the printer references a previous print status based on the print status stored in the storage means and, if the previous print operation is not completed, ejects the recording paper for a maximum print length and cuts the ejected recording paper.

Abstract: A method of feeding an ink ribbon for a printer in which the ink ribbon is frequently reused for printing action by reversing the feeding of the ribbon at the ribbon ends including suppressing the printing action of the printer for a predetermined time at the time of reversing the feeding of the ribbon at the ribbon end to prevent the ink ribbon from excessive use at the ribbon ends to prolong the useful life of the ribbon.

Abstract: A control system for an impact printer having a cooling fan, in which a current for driving a printing device is detected as a voltage and the detected voltage is compared with a reference value. When the detected voltage is lower than the reference value, the current for driving the cooling fan is decreased.

Abstract: A dot printer comprising a power system for supplying power to a load; a setting circuit for setting a reference voltage value corresponding to a predetermined output current value within a range not in excess of a maximum rated output current of the power system; a detecting circuit for detecting an output value of the power system and for providing a voltage value corresponding to the output value; and a control circuit for comparing the voltage value provided by the detecting circuit with the reference voltage value of the setting circuit and controlling a printing operation to change the reciprocating printing by the print head from a bidirectional printing to a unidirectional printing when the voltage value provided by the detecting circuit is greater or smaller than the reference voltage value of the setting circuit.
