An information processing system includes: a storage unit that stores first printing information on already executed printing in association with an image for printing converted from the first printing information; and an execution unit that, when second printing information included in a printing instruction which instructs execution of printing is identical to the first printing information stored in the storage unit, executes printing according to the printing instruction using the image for printing.

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.

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 graphical object processor 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 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 printing apparatus, including a printing device, a communication interface, a memory, and a controller, is provided. In a case where the controller determines that an image in image data is to be rotated and that a predetermined condition is satisfied, the controller conducts rotation of the image in the image data concurrently with rasterization of the image data and stores raster data including the rotated image in the memory. In a case where the controller determines that the image in the image data is to be rotated and that the predetermined condition is not satisfied, the controller conducts rasterization of the image data without rotating the image in the image data, and rotates a raster image in the raster data stored in the memory and generates the print data from the raster data including the rotated raster image.

A printing computing device connects to a multi-function printing (MFP) device to enable additional functionality and capabilities not offered by the MFP device. The printing computing device connects to a network to receive print jobs from external devices within the network. The printing computing device processes the print jobs according to rules such that print jobs are processed accordingly. The printing computing device also includes firmware not available on the MFP device such that print jobs not supported by the MFP device still may be processed. The printing computing device also includes an engine that determines whether an incoming print job is a PDL print job or a command to perform a function not available on the MFP device.

An information processing system includes: a storage unit that stores first printing information on already executed printing in association with an image for printing converted from the first printing information; and an execution unit that, when second printing information included in a printing instruction which instructs execution of printing is identical to the first printing information stored in the storage unit, executes printing according to the printing instruction using the image for printing.

A method for generating bitmap image data of a page includes acquiring print data of a page including compressed images, and performing rendering of bands included in the page based on the print data to generate the bitmap image data. The performing of the rendering performs rendering at least two of the bands concurrently. The performing of the rendering includes decompressing the compressed images, and using the decompressed images for corresponding bands of the bands to generate the bitmap image data. The decompressing decompresses, into a same memory area in a decompression buffer, at least two compressed images used for different bands, so that one of the two compressed images is decompressed into the same memory area and another of the two compressed images is decompressed, after rendering of a last band for which the one of the two compressed images is lastly used is finished, into the same memory area.

A printer includes an input device for receiving an input operation to the printer from a user, a memory, a printing device, and a controller. The controller is configured to: receive print data from a terminal; in a case where the controller determines that the print data received from the terminal is raster data, determine whether a particular condition is met; in a case where the controller determines that the particular condition is met, send, to the terminal, request information that requests the terminal to send page description language (PDL) data; and, in a case where the controller receives the PDL data from the terminal after sending the request information to the terminal, allow the printing device to execute printing on a basis of the PDL data. The PDL data specifies types of drawing objects and drawing positions with commands.
