A printing system includes a printing device, a color management server, and a client device. An estimated ink use is determined for a print job within printing system. After printing operations, a baseline average ink use is determined for a set of printed pages of the print job. If the baseline average ink use varies from the estimated ink use, then a corrective action is taken to adjust ink use to be closer to the estimated ink use. The corrective action is a global corrective action for the entire document of the print job or a targeted action that adjusts only specified features or pages of the document.

An image forming apparatus comprises: an obtaining unit configured to obtain a first printable amount corresponding to an upper limit on printing according to the first printing mode and a second printable amount corresponding to an upper limit on printing according to the second printing mode; a changing unit configured to, in a case where an amount to be printed by a job designating printing according to the first printing mode being executed exceeds the first printable amount, under a condition that the second printable amount would not be exceeded, change the printing according to the first printing mode designated by the job to printing according to the second printing mode; and an execution unit configured to execute the job after the change by the changing unit to printing according to the second printing mode.

In an image forming apparatus, a consumable accommodates printing material and is mounted in a main casing. The consumable includes a consumable memory. A controller performs a restriction process to rewrite the first status information to indicate the used product to prohibit the consumable from being used in other image forming apparatuses in a case where first status information stored in the one of the consumable memory and a main memory indicates the new product. The controller performs an updating process to update the second status information so that the second status information indicates that the consumable can be temporarily used in the another image forming apparatus in a case where the controller receives a contract cancellation instruction. The contract cancellation instruction instructs to cancel an agreement concluded for the image forming apparatus.

An image processing apparatus includes a processor configured to: in response to a prior print instruction, impose multiple pieces of prior image data to a subset of multiple imposition regions of a continuous paper sheet that is enabled to be imposed with the prior image data in response to the prior print instruction; and in response to a subsequent print instruction, impose subsequent image data to an unplanned region that is not imposed with the prior image data, from among the imposition regions serving as targets of imposition after the prior print instruction.

According to examples, an apparatus may include a processor and a memory on which is stored instructions that when executed by the processor, cause the processor to determine that data stored in a memory device of a printer cartridge installed in a printing device is to be updated. The printing device may be in remote communication with the apparatus via a network connection. The instructions may also cause the processor to identify update data that is to be used to update the data stored in the memory device. The instructions may further cause the processor to communicate, via the network connection with the printing device, the identified update data to the printing device. The printing device may update the data stored in the memory device of the printer cartridge with the update data.

The character edge area determining unit (21) determines a character edge area in input image data.

The output image processing unit (12) performs an image process for a target pixel in the determined character edge area in order to adjust a toner consumption amount in accordance with the number of continuous edge pixels (i.e. continuous pixels that belong to the character edge area) included in a reference window of which a center is set on the target pixel and an average value of pixel values of the continuous edge pixels.

An image processing apparatus includes: a controller configured to: control a reader to read an image on a reading medium; determine whether a preview image corresponding to the read image is to be displayed on a display, based on a setting value for a setting item, reading-obtained information, or the setting value and the reading-obtained information, in a case where the controller determines that the preview image is to be displayed, control the display to display the preview image, and execute a particular processing based on obtained read-image data in a case where a processing instruction is input after the preview image is displayed; and in a case where the controller determines that the preview image is not to be displayed, execute the particular processing based on the read-image data without displaying the preview image.

An image forming apparatus that is capable of wireless communication with an operation device and that can be operated by the operation device via the wireless communication, the image forming apparatus comprising: an image forming unit configured to perform image formation on a sheet based on a print execution instruction sent from the operation device via the wireless communication; a reading unit configured to perform reading of an image formed on the sheet based on a scan execution instruction sent from the operation device via the wireless communication; and a controller that, during a period of time from the time one user logs in the image forming apparatus until the user logs out, (1) is configured to prohibit the print execution instruction using an operation device by other user who has logged in using the operation device, and (2) is configured to permit the scan execution instruction using the operation device.

An image forming apparatus includes a main memory, and a controller. The main memory stores mode information indicating whether the image forming apparatus is set to a contract mode, upper limit information indicating an upper limit to which printing can be performed during a prescribed period, and actual print sheet number information indicating an actual print sheet number actually printed during the prescribed period. The performs a printing permission process in a case that mode information indicates the contract mode and the actual print sheet number is less than the upper limit when the controller receives a print job even in a case that a sum of a specific print sheet number specified in advance in the print job and the actual print sheet number is greater than the upper limit, the printing permission process permitting printing for the specific sheet number as a permission print sheet number.

A printing apparatus comprises: a print portion configured to perform printing on a print medium drawn from a rolled medium; and a print controller configured to cause the print portion to print status information in response to an instruction to print the status information. The print controller is configured to cause the print portion to print first status information, which is part of the status information, cause the print portion to print at least one of selection items corresponding to pieces of status information, and cause, when at least one printed selection item is selected, the print portion to print second status information corresponding to the selected selection item.
