Abstract: A system prints a document by generating a device-dependent font that is appropriate for the document and the print device. The system does this by identifying a font for the document, identifying an affine transformation matrix for the font, using the device resolution and current page location of the print device to modify the affine transformation matrix to yield a current transformation matrix, adding a reverse of the current transformation matrix to the affine transformation matrix to yield a modified font matrix, and generate a print file using the modified font matrix. The print device then uses the print file print the document with a font corresponding to the modified font matrix.

Abstract: Provided is a document file output apparatus capable of appropriately storing each document as different files depending on a difference in printing setting, even when printed materials which are to be different documents for each single sheet or every plurality of sheets are continuously read, a document file output method, and a computer readable medium storing a program for operating a computer as the document file output apparatus. The document file output apparatus each specifies the printing setting of each read printed material, for example, a layout, a difference in a size of the read printed material, presence or absence of framework printing, presence or absence of reduction printing, color/monochromatic setting, or image embedding, from the obtained image data, and outputs by dividing the document files before and after the read printed material in which the printing setting is changed.
Abstract: Systems and methods for securely printing an electronic document. The electronic document is received as a print job at a secure print service system from a user device. The secure print service system generates a job name and a password for the print job by the secure print service system. The secure print service system then transmits the job name for the print job to a network printer communicatively coupled to the secure print service system. At the network printer, a recipient password is received from the network printer. Then, the secure print service system authorizes the printing of the document at the network printer based on comparison of the recipient password received from the network printer and the password generated by the secure print service system.

Abstract: An image is read from a recording medium via first and second optical imaging systems disposed such that respective reading regions partially overlap each other in a principal scanning direction on a reading surface. A sum of distances over which first and second images captured by the first and second optical imaging systems, respectively, are displaced in the principal scanning direction with respect to a reference point included in a region in which the reading regions overlap each other is calculated. First and second distances, over which the first and second images are displaced in the principal scanning direction, respectively, are calculated using the sum and first and second reading angles at which the first and second optical imaging systems, respectively, read the reference point. Positions of the first image and the second image in the principal scanning direction are corrected using the first distance and the second distance, respectively.

Abstract: In an image-reading device, a counting unit counts a number of clock cycles of a spread-spectrum clock as a counter value. A correcting unit corrects one of the counter value and a reference clock cycle number based on a phase detected by the phase detecting unit when the counting unit counts. A comparing unit compares the counter value and the reference clock cycle number and determines whether the counter value and the reference clock cycle number satisfy a prescribed relationship. A time length setting unit sets a length of at least one of a reading time and an irradiation time based on: a timing when the counting unit starts counting to set the time length; and a timing when the comparing unit determines that the compared values satisfy the prescribed relationship, such that the time length set by the time length setting unit remains constant.

The method and system further comprises storing the print job in a queue associated with the server, transmitting the print job to a specified printer when one of at least one recipient requests rendering of the print job, and rendering the print job at the specified printer for one of the at least one recipients.
Abstract: A control method for controlling a printing system includes selectively executing an inline job and an offline job. The inline job is for executing post-processing on a sheet printed by a printing apparatus by using a post-processing apparatus and the offline job is for executing post-processing on a sheet without executing printing by the printing apparatus by using the post-processing apparatus. The control method also includes restricting execution of the inline job if a sheet has been set in a paper feed unit that is a paper feed source of the offline job to be executed.

Abstract: The disclosure is directed towards a system and method for using a multicore processor to process a printer definition language (PDL). The system improves efficiency by supporting parallel processing of many commonly used PDLs, while also supporting serial processing of many legacy PDLs. When processing a PDL, the system relies on several stages, including a parsing stage, a printer drawings services stage, and a graphic services stage, which includes order generation. The system provides flexibility by permitting function calls of common PDLs to be either asynchronous requests or blocking synchronous requests. Because legacy PDLs are executed serially, legacy PDL requests are considered to be blocking synchronous requests. The system provides a level of abstraction at the PDL level by allowing multiple requests to be combined into a compound asynchronous request. The system also improves accuracy by notifying the original caller of a request about an error during error handling.
