Abstract: An image forming apparatus comprises a communicator that receives a print command of image data from a user terminal via a network; an image former that forms an image on the basis of the image data; and one or more controllers that control the communicator and the image former, wherein when a time-out period set in advance has elapsed without receiving a transmission completion notification of a print command from the user terminal after receiving the print command from the user terminal, the one or more controllers determine whether image data related to the print command is complete or not in accordance with a determination procedure set in advance, and when the one or more controllers determine that the image data is complete, the one or more controllers cause the image former to form an image based on the image data, while when the one or more controllers determine that the image data is not complete, the one or more controllers withhold execution of the print command.

Abstract: An image forming apparatus includes a CPU, the CPU stores, in an HDD, a print job received via a network connection circuit. The CPU analyzes PDL data for each page of the print job, and executes a PDL process for generating bitmap data. When an unrecoverable error occurs in analyzing of the PDL data, only the PDL process is restarted, a print job in which an unrecoverable error occurs is re-input, and analysis is resumed from the page in which the unrecoverable error occurs. When an unrecoverable error occurs on the same page again, only the PDL process is restarted again, the page in which the previous unrecoverable error occurs is skipped, and analysis and printing of a next page are performed.

Abstract: The invention provides an image-forming apparatus that includes a printer that performs printing, and a controller that determines, on a basis of settings related to a print job, whether to execute the print job as a print job related to test printing or execute the print job as a normal print job, and causes the printer to perform printing, in which the settings related to the print job include a plurality of items, and one or more combinations of a setting of another item with respect to a setting of one item are set as recommended settings, and, when the print job includes a setting of the another item other than the recommended settings with respect to the setting of the one item, the controller determines that the print job is a print job related to test printing.
