The conventional laser beam printer has to execute serial communication periodically or whenever necessary, with respect to the status change which is not reflected in the /RDY signal, and the serial communication is indispensable for each printing operation, particularly in case the auto sheet feeding function is selected, and such serial communications constitute an overhead in the process. The present invention provides an output control apparatus provided with an output unit for converting data received from the external device into an output image and outputting such output image, the output control apparatus comprising a detection unit for detecting the presence or absence of a change in the status of the output unit, an acquisition unit for acquiring, in case the detection unit detects a change in the status of the output unit, detailed information of the status showing such change, from the output unit, and a transmission control unit for effecting control in such a manner that status information based on the detailed information is transmitted from the transmission unit to the external device.
An output control apparatus having an output unit for converting data received from an external device into an output image and outputting the output image, comprising:
An output control method for use in an output control apparatus having an output unit for converting data received from an external device into an output image and outputting the output image, comprising steps of:
A memory medium storing a computer-readable program for use in an output control apparatus provided with an output unit for converting data received from an external device into an output image and outputting such output image, wherein said program comprises:
