In the print data for a nozzle of a printer, white dots are replaced by pre-ejection pulses. One or more repetitions of the pre-ejection pulses may be inserted into the print data, depending on the actual print speed of the printer, to determine print speed-dependent print data with which the nozzle is activated to print a print image with high print quality.

An image formation apparatus includes a communication unit, a controller, an operation unit, and an image forming device. The communication unit is configured to receive, as a printing job, a printing setting and printing data. The printing setting includes a size corresponding to one of a longitudinal-feed envelope and a lateral-feed envelope, but does not designate which of the longitudinal-feed and lateral-feed envelopes undergoes printing. The raster image generator is configured to generate a raster image corresponding to the longitudinal-feed envelope and a raster image corresponding to the lateral-feed envelope in accordance with the printing data. The operation unit is configured to display a screen that receives a selection between the longitudinal-feed and lateral-feed envelopes to receive the selection made by a user. The image forming device is configured to perform printing with the raster image corresponding to the longitudinal-feed or lateral-feed envelope selected.

An information processing apparatus includes a processor configured to perform a first process of generating a rasterized image by rasterizing received image data, perform a second process of generating rasterized images by rasterizing the received image data plural times by a processing unit that performs the first process, and contrast the rasterized image obtained by the first process with the plural rasterized images obtained by the second process performed plural times, and check whether the rasterized image obtained by the first process is invalid.

An non-transitory computer readable medium stores a program causing a computer installed in an information processing device to execute a process corresponding to a printer connected to the information processing device. The process includes receiving image data for images of a plurality of pages from a general-purpose print program which is pre-installed in an OS of the computer, generating composite image data corresponding to an composite image which is generated by reducing images of the plurality of pages in size and arranging the reduced images for the N pages so that the reduced images fit on one surface of the sheet, from the image data received in the receiving of the image data, and causing the information processing device to transmit print data which is rasterized based on the composite image data to the printer.

An image processing device includes an input device and circuitry. The input device inputs data. The circuitry converts text information to be printed included in the data to generate converted information and outputs data for image formation including the converted information.

In an example, a method comprises: receiving, at a raster image processor, image data representing a print job, the image data representing an area to be printed using a process color separation and an area to be printed using a spot color; producing at the raster image processor, a first rasterized image representing a layer of the print job having the process color and a second rasterized image representing a layer of the print job having the spot color; receiving at an emulator, the second rasterized image; and representing, by the emulator, the second rasterized image as a plurality of constituent process color separation layers.

An information processing apparatus that manages print processes of plural printing apparatuses, the information processing apparatus includes a processor configured to acquire execution information indicating an execution status of each printing apparatus from the plural printing apparatuses, in a case in which a predetermined condition regarding processing of converting print data into a raster image is satisfied in one printing apparatus, extract another printing apparatus capable of executing the processing of converting the print data into the raster image from among other printing apparatuses other than the one printing apparatus by using the execution information, cause the other printing apparatus, that is extracted, to execute the processing of converting the print data of a print job scheduled to be printed in the one printing apparatus into the raster image, and perform control to transmit the raster image created by the other printing apparatus to the one printing apparatus.

A printer is caused to perform duplex printing by an information processing device in which an OS standard printing program is installed. When causing a printer connected to a PC to execute duplex printing based on a print instruction output from an editing application installed in the PC, an auxiliary program that supports the printer executes rotation processing of rotating an image of a page, which is required to be rotated, by 180° for intermediate data received from a general-purpose print program, executes rearrangement processing of rearranging a processing order from a page order to a print order for print data received from the general-purpose print program, according to a sheet conveying aspect of the printer, and transmits the print data after the rotation processing and the rearrangement processing from the PC to the printer.

In a method and device for ascertaining print data for a print image to be printed, the print data is adapted and/or determined such that the time curve of the ink flow quantity, exhibits no quantity changes or flow rates due to which ink ejection errors might be produced, in particular nozzle failures. The device includes: a communication interface configured to receive the print data; and processing circuitry that ascertains, based on the print data, a time curve of an ink flow quantity of ink that, during the printing of the print image, flows in the print bar and/or is ejected from the one or more nozzles of the print bar; and determine, based on the time curve of the ink flow quantity, whether an ink ejection error will be produced.

In a printer, when a storage print job is a print job for execution of carbon-copy printing, a controller performs: creating a plurality of bit map data by rasterizing page-description-language data contained in the storage print job a plurality of times; storing the created bit map data; and controlling an image former to print images based on the stored bit map data when a print instruction for the storage print job is received. When the storage print job is a print job not for execution of the carbon-copy printing, the controller performs: storing the page-description-language data contained in the storage print job; when the print instruction for the storage print job is received, rasterizing the stored page-description-language data to create bit map data; and controlling the image former to print an image based on the created bit map data.
