In processing using a print data processing apparatus that parallelly interprets pages of print data, in the case where a command to reset the number of already interpreted pages is included in the print data, a certain page to be printed is not printed. In the case of detecting a command to invalidate contents interpreted hitherto, an interpreter stores the number of already interpreted pages at the time in point of the detection of the invalidation command in a cache. Then, the interpreter generates intermediate data in the case where the sum of the cached value and the number of already interpreted pages managed by the interpreter coincides with a processing-target page number.

A printed-material check apparatus includes a processor configured to: acquire check information including section information and first comparison information from a printed material printed on a basis of print data with check information, the section information identifying a section in print data, the first comparison information being generated from data identified by the section, the print data with check information being generated by adding the check information to the print data; acquire an image of an inner part of a section on the printed material, the section being identified by the acquired check information; and determine whether the printed material is valid by using the first comparison information and the image of the inner part of the section on the printed material.

Provided is an image forming apparatus for further speeding up an image forming process. A first rendering core of a rendering core module executes data analysis of an object of PDL format printing information. A second rendering core executes a speculative process for generating a Display List for an object. A third rendering core executes a rendering process for a printout or display output based on the Display List generated by the second rendering core. In addition, data analysis by the first rendering core and the speculative process by the second rendering core are executed in parallel processing. As a result, the second rendering core can execute the generation of a Display List by a speculative process even without receiving a rendering command from the first rendering core.

An image forming apparatus includes a interpretation unit, a memory control unit, and an execution unit. The interpretation unit is configured to interpret print data described in a page description language. The memory control unit is configured to control allocation a memory area to the interpretation unit. The execution unit is configured to execute printing by making the interpretation unit to which the memory area is allocated interpret the print data. The memory control unit releases the allocated memory area according to a time elapsed after the print data is interpreted without at least interpretation of print data being performed using the interpretation unit to which the memory area is allocated.

An image processing apparatus includes: an extraction unit configured to extract a written image additionally written on printed matter on which a document is written from a read image read from the printed matter; and a generation unit configured to generate additionally written document data by writing written image information about the written image into document data that is the document described in a mark-up language.

An apparatus that performs image processing on input image data in parallel in units of block according to an aspect of the invention includes a derivation unit configured to derive a memory size used in conversion processing of converting data alignment sequence in the image data from a line sequence into a block sequence which is executed before rendering of the image data and a memory size used in the conversion processing which is executed after the rendering of the image data, a determination unit configured to determine a timing for executing the conversion processing based on the derivation results, and a conversion unit configured to execute the conversion processing at the determined timing.

A printer driver has a single filter. The filter includes a program for constructing a pipeline consisted of a plurality of stages based on a print ticket. In one or more of the plurality of stages, a content box of print-target data is modified. When the content box is modified, commands respectively indicating affine transformation matrices are generated. The commands are pushed into a command stack. The pushed commands are used for modification of a visual element. Specifically, the affine transformation matrices are multiplied and thereby an integrated transformation matrix is generated. The visual element is modified by multiplying an affine transformation matrix of the visual element by the integrated transformation matrix.

An apparatus and method for setting authentication information of an information processing apparatus is provided. When a setting of a password to a PostScript (PS) interpreter is performed by a PS command, the password is stored in a volatile memory. When the setting of a password to the PS interpreter is performed through a setting screen, the password is stored in a nonvolatile memory, and thereafter, stored in the volatile memory.

A method, an image forming apparatus, and a computer program product are disclosed for applying policy to one or more page description languages or page description language transfer protocols. The method includes creating a command group which comprises two or more printer language commands and/or another command group of printer language commands, wherein, the two or more printer language commands are selected from one or more page description languages or page description language transfer protocols; storing a printer language policy in an image forming apparatus, the printer language policy configured to control access to the command group for one or more users; applying the printer language policy to the command group; and when a user requests a job comprising printer language commands, executing the job based on the printer language policy assigned to the user.
