PURPOSE:To prevent an operator from being forced to wait for operation by checking whether or not a preferential output instruction exists during the operation of a normal output and performing the computation of the preferential output instruction when the preferential output instruction exists. CONSTITUTION:A normal flag #1 or interrupt job flag #2 is added to every one page of output instructions prepared at a workstation 300 as an identifier for indicating whether or not the instructions are to be preferentially outputted. The output instructions are transferred to an image setter 400 and stored in the normal output instruction section 430A or preferential output instruction section 430B of a main memory section 430. During an output page is computed at the time of a normal output, whether or not a preferential output instruction exists in the section 430B or not is checked whenever one command is interpreted. When the preferential output instruction exists, computation of the preferential output instruction is preferentially computed. Therefore, the operator of the workstation 300 is not forced to wait until one page of the block copy outputting page computation is completed when the operator starts computation for a proofer. |
