Abstract

A control device for use with an image recording apparatus receives data indicative of a malfunction of the image recording apparatus and other data indicative of the completion of the transfer of image data for a unit set of drawings from a host computer, and then informs the host computer of the malfunction occurrence in the image recording apparatus. With such an arrangement, even when a malfunction occurs in the image recording apparatus, the graphic data for a unit set of drawings generated by the host computer, which in turn is converted into image data, may be ceaselessly transferred to and temporarily stored in an image memory in the control device. When the image recording apparatus is restored to a normal state, the control device reads out the image data drawings from the image memory, and transfers again the image data to the image recording apparatus.
