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.

Image forming apparatus conducting an interpretation operation

Image processing apparatus and method to perform an image processing job based on a received processing request, which includes a processing condition set by a user. Error protection is performed to detect a job setting error caused by a mismatching between the processing condition of the image processing job and a processing capability of the image processing apparatus. Error information relates to a previously detected air that is the job setting error previously detected. Error report conditions indicate whether the previously detected air has a same condition as the processing condition of the image processing job. Error information is managed to store information relating to the currently detected error when the currently detected error satisfies an error storage condition, determine whether the currently detected satisfies the error report condition and generate an error report to notify the user and an administrator when these conditions are satisfied.

Managing and utilizing error information relating to image processing

A printing apparatus receives a plurality of print jobs containing print data from a host computer connected thereto through a network. The printing apparatus temporarily stores the print job in a storage unit to print the print data. The printing apparatus receives a request to pause or restart printing of a print job, and controls execution of the print job in response to the request. Upon receiving a request to restart a print job being paused, the printing apparatus determines a printing order according to a predetermined condition to print the print job.
