A document generation system generates a plurality of form data of a first file format from document data; converts the plurality of form data of the first file format into a plurality of form data of a second file format; causes a display unit to display the plurality of form data of the converted second file format so as to be able to accept a storage request; and, in response to accepting a storage request for the plurality of form data of the second file format displayed on the display unit, combines the plurality of form data of the first file format corresponding to the plurality of form data of the second file format into data of the first file format and store the combined data in a storage unit.

According to an example, a printing system may include printing components, an input voltage engine to determine whether an input voltage level is outside of a predetermined voltage level range, and a printing components engine to control the printing components to operate in one of a normal mode and a reduced throughput mode based upon whether the accessed input voltage level is outside of the predetermined voltage level range.

Provided are an image forming apparatus for outputting a plurality of images having different sizes according to a method pre-set by a user without interrupting a current printing operation when the plurality of images having different sizes are obtained and a method of operating the image forming apparatus.

An image processing apparatus decides first growth points indicating positions at which dots for generating a screen having a low ruling are generated based on a predetermined screen ruling and screen angle, and second growth points that indicate positions at which dots for increasing the screen ruling of a screen represented by the first growth points are generated. The apparatus generates a screen for growing, in accordance with increase in pixel values of an input image, dots generated centered on the first growth points, and switching, when the pixel values exceed a threshold value, growth points from the first growth points to the second growth points, and growing, in accordance with increase in the pixel values, dots generated centered on the second growth points, and uses the generated screen for screen processing on image data to be printed.

A printing system includes a printing device. The printing device includes a raster image processor (RIP) system that renders pages of a print job for printing. The RIP system processes pages of the print job in parallel. It also processes job is parallel. If an error occurs when processing a page using a standard RIP, then the RIP system activates a failover RIP. The failover RIP uses a different strategy for processing the page than a standard RIP. The failover RIP is configured to implement the strategy. A failover queue is used to store error pages to wait for processing by the failover queue. The processed page is outputted from the failover RIP to a front end of the RIP system.

An information processing device includes: a data generating section generating compatible format data of application data; a selecting section causing selection of an output process among plural types of output processes that can use the compatible format data; a searching section searching image output device(s) connected on a network and extracting just an image output device at least capable of carrying out the selected output process; a disclosure/reception section disclosing the image output device extracted by the searching section and receiving (a) a selection of an image output device serving as a compatible format data transmission destination, (b) an entry of an output setting, and (c) an instruction for executing the output setting; and a command generating section generating a command for causing the selected output process to be executed based on the entered output setting, upon receiving the instruction for executing the output process from the disclosure/reception section.

A recording apparatus performs converting each of recording data and control data for controlling a recording head into transfer data in a command format and transmitting the transfer data to the recording head via a transmission path, and detecting, in the recording head, an error in the received transfer data, and, in the transmission after detecting the error, reconstructs next transfer data in such a manner that a command that has been included in the transfer data in which the error has occurred among commands concerning the control data and that is scheduled not to be included in the next transfer data is included in the next transfer data, and then transmits the next transfer data reconstructed.

A method for transmitting a parameter of a storage chip of an imaging cartridge, a storage chip and an imaging cartridge are provided. The method includes: receiving an instruction transmitted by a print imaging device; and determining that the instruction is an instruction for reading a key parameter, and transmitting the key parameter to the print imaging device, where the key parameter is generated by the storage chip. In the application, the parameter to be read by the print imaging device is generated by the storage chip. When the printing imaging equipment transmits the reading instruction, the storage chip transmits the parameter generated by itself to the print imaging device. Therefore, the parameter cannot be directly read by the printing imaging equipment at any moment, and thus a certain important parameter in the storage chip can be prevented from being obtained maliciously.

An image forming apparatus includes a fixing device and circuitry. The fixing device includes a pair of rotators and a heater. The pair of rotators forms a nip through which recording media pass in a conveyance direction. The heater heats at least one of the pair of rotators to fix images printed on the recording media. The circuitry is configured to acquire image data of the images to be printed on the recording media within three minutes after a start of printing the images on the recording media and set an output of the heater to be lower than a predetermined reference value within the three minutes after the start of printing based on the image data.

There are provided a circulation path which can supply printing material to a printing element board having nozzle capable of ejecting printing material and collect printing material not ejected from the printing element board, an acquisition unit which acquires information on concentration of printing material circulating through the circulation path, and a discharge control unit which executes discharge control of printing material concentration in which printing material is discharged from the circulation path and the circulation path is supplied with an amount of printing material corresponding to a discharge amount according to the information on concentration. In a case where the discharge control is executed, the discharge control unit selectively executes one of first discharge control in which a discharge amount of printing material concentration is a first discharge amount and second discharge control in which the discharge amount is a second discharge amount greater than the first discharge amount.
