Abstract:
1. An image forming device which forms an image based on input data, comprising: an output sequence storing unit storing information concerning the input data, and storing an output sequence according to a reception sequence of reception of items of the information; a priority determining unit determining a priority of outputting the input data; an output sequence changing unit changing the output sequence stored in the output sequence storing unit in accordance with the priority determined by the priority determining unit; a plurality of PDL interpreter units performing image expansion of the input data; and a PDL control unit controlling the plurality of PDL interpreter units to perform image expansion of the input data in accordance with the output sequence stored in the output sequence storing unit, wherein, when the priority of outputting the input data determined by the priority determining unit is higher than a priority of in-process data during the image expansion performed by at least one of the plurality of PDL interpreter units, the PDL control unit determines whether the at least one of the plurality of PDL interpreter units supports an interruption process, and the output sequence changing unit changes the output sequence stored in the output sequence storing unit such that, when the at least one of the plurality of PDL interpreter units supports the interruption process, another of the plurality of PDL interpreter units performs image expansion of the input data earlier than the image expansion of the in-process data, and when the at least one of the plurality of PDL interpreter units does not support the interruption process, another of the plurality of PDL interpreter units performs the image expansion of the input data later than the image expansion of the in-process data.
