In a printing apparatus, a controller is configured to: receive compressed image data; store the compressed image data into a memory; individually identify partial compressed data in the stored compressed image data, the partial compressed data corresponding to separate images; store the partial compressed data into the memory or store information identifying each of the partial compressed data, into the memory; a first creating processing for decompressing one of the partial compressed data and creating print data based on partial decompressed data obtained by decompressing the one partial compressed data; and a first output processing for outputting the created print data. The controller repeats the first creating processing and the first output processing a number of times corresponding to the number of the partial compressed data. The printing apparatus performs printing based on the print data output in the first output processing.

An image forming apparatus includes circuitry to receive a file including data of a plurality of pages and position information indicating individual positions of data of the plurality of pages. The circuitry further starts printing of one of the plurality of pages based on data specified by specifying information that indicates a position of data of one of the plurality of pages. The circuitry further starts the printing of one of the plurality of pages when receiving the specifying information before the position information.

Provided is an image forming apparatus capable of executing a copy job without causing a memory shortage by dividing and sequentially executing the copy job process. The image forming apparatus includes a free area determining unit and a division process executing unit. The free area determining unit compares capacities of work areas necessary for executing a scanning job and a printing job with free area in memory (RAM), respectively. The division process executing unit, in a case where the free area determining unit determines that the free area in memory is equal to or greater than the capacity of the work area necessary for executing the scanning job, but is less than the capacity of the work area necessary for executing the printing job, cancels parallel processing, and after executing the scanning process, saves in a non-volatile memory, and then after restarting, executes the printing process.

Embodiments herein describe a two-phase printing process that utilizes page-to-resource tracking during the first rip-to-spool phase in order to perform resource scheduling during the second print-from-spool phase. In one embodiment, compute nodes include a RIP and a raster builder. A controller receives a print job, identifies a distribution of logical pages in the print job to the compute nodes, and generates page assignment information that maps the logical pages to the compute nodes based on the distribution. The compute nodes rasterize the logical pages to generate intermediate data using the RIPs, and store the intermediate raster data at a RIP spool. The controller directs a distribution of the intermediate raster data from the RIP spool to the compute nodes based on the page assignment information, and the compute nodes assemble the intermediate raster data into complete raster data using the raster builders.
