摘要： A communications buffer and control unit that configure a USB connection endpoint are provided connected by a USB bus to a host device. The control unit changes the receive buffer size of a receive buffer where the communications buffer stores receive data, based on an instruction that is sent from the host device side through USB virtual serial communication, to enable the reception of real-time execution commands by the communications device. This enables the reception of real-time execution commands when the receive buffer on the communications device side is in a buffer-full state in data communications between a host device and a communications device.

摘要： When a period from the point of time of receipt of instruction information concerning a cutting instruction to the point of time of receipt of instruction information concerning a printing instruction subsequent to the receipt of the instruction information concerning the cutting instruction has reached a prescribed period, a recording medium is cut and conveyed in a reverse direction by a prescribed distance, and then new printing is started. When the period from the point of time of receipt of the instruction information concerning the cutting instruction to the point of time of receipt of the instruction information concerning the printing instruction subsequent to the receipt of the instruction information concerning the cutting instruction has not reached the prescribed period, the recording medium is cut and then new printing is started without convey of the recording medium in the reverse direction.

摘要： Upon supply of electric power to a printer, a dot pulse is generated from a dot pulse generator each time a carriage driving motor rotates for a predetermined rotational angle, and thereafter, an output of a home position sensor falls when a carriage reaches its reference moving position. When a microprocessor determines that the leading edge of a dot pulse, generated for the first time after the generation of the trailing edge of the sensor output, is undetectable due to the presence of a closed timing relationship between the trailing edge of the sensor output and the leading edge of the dot pulse, on the basis of one period of the pulse generator output and a time period from an instant at which the trailing edge of the sensor output is generated to an instant at which the leading edge is detected, the microprocessor supplies a high level signal to an exclusive OR circuit, connected to the pulse generator, so as to invert the polarity of the detection edge of the dot pulses, to thereby prevent the closed timing relationship so as to prevent the leading edge of the dot pulse from being undetected, whereby a variation in printing positions is reduced.
