Patent attributes
An image forming apparatus for forming images by outputting plural image data in an order corresponding to an input order of plural input data is disclosed. The image forming apparatus includes a data receiving part for receiving the input data, a priority determining part for determining priority of outputting the input data, a PDL process part having plural PDL interpretation parts including at least first and second PDL interpretation parts for performing a PDL process on the input data, and a PDL control part for controlling each of the plural PDL interpretation parts, wherein when a subsequent input data is determined to have a priority higher than that of a prior input data in a case where the first PDL interpretation part is performing a first PDL process on the prior input data, the PDL control part is configured to stop the first PDL process and cause the second PDL interpretation part to perform a second PDL process on the subsequent input data.
