Abstract: Upon completion of print data transmission, the host terminal sends to a network printer a finish command via a print port and further a forced disconnection request command via another communication port. If the finish command is lost due to a network failure, the network printer forcibly disconnects the host terminal from the print port of the network printer in response to the forced disconnection request command, thereby allowing the other host terminals to use the network printer without waiting the elapse of the time-out period.

Abstract: In a printer, an MPU makes a flash ROM store a temperature read by a temperature sensor at the time of setting of a correction value and a misalignment correction number indicating a misalignment correction value. At the time of reciprocating print motion of a printer, the printer makes the temperature sensor measure an actual ambient temperature before backward printing and obtains a difference between the present temperature and the temperature at the time of setting of the correction value. A print start delay time which indicates timing between a point of time of driving a carriage motor and a point of time of starting the backward printing is corrected in accordance with the temperature difference. The printer starts the backward printing at the timing delayed for the corrected print start delay time.

Abstract: A Printer includes an interface for exchanging signals with an external host, an interface for exchanging signals with a peripheral device, a station for printing a recording medium based on print data supplied by the external host, and a CPU for performing an output through operation to transmit data received from the external host via interface to the peripheral device via interface, and an input through operation to transmit data received from the peripheral device via interface to the external host via interface. This construction allows connection of a larger number of peripheral devices than the number of connection ports of the external host.

Abstract: A printer in which print densities of print heads can be adjusted simply and rapidly and set to have an optimum impact force, and a method of adjusting a print density are provided. Concretely, print density patterns which can be set at regular steps toward the high and low density sides of a predetermined density are generated. On the basis of the print density patterns, printing is conducted on a recording medium. A pattern in which a desired print density appears is selected and the print densities of the print heads are absolutely or relatively adjusted.
