An example system may include a processor and a non-transitory machine-readable storage medium storing instructions executable by the processor to determine, during an imaging operation by an imaging component of a printing device, whether a print queue, supplied by the imaging component, will be depleted by a printing component of the printing device prior to a completion of the imaging operation; and adjust, based on the determination, a media feed rate of the printing component.

Systems and methods are provided for print review systems. One embodiment is a print review system that includes a memory that stores inspection parameters of print media marked by a printer, an interface that communicates with the printer, and a controller that, in response to the printer initiating processing of a print job, receives an indication via the interface of settings used by the printer in processing the print job, modifies the parameters based on the settings, inspects the print media based on the modified parameters, and reports compliance of the print job with the modified parameters.

A server system connectable to a print system including a transmission unit configured to transmit received print data to a printer includes an acquisition unit configured to acquire information indicating an amount of a consumable which is used for printing of transmitted print data to the printer, and a placement unit configured to place an order for the consumable to be used by the printer, based on the acquired information.

An information processing apparatus acquires printing setting information including at least information on a sheet type relating to mounted sheets and information on a sheet width, which correspond to each sheet feed unit in a printing apparatus capable of feeding sheets from a plurality of sheet feed units, creates a first item for designating a plurality of sheet feed units whose both sheet type and sheet width are the same among sheet feed units of the printing apparatus, and a second item for designating a sheet feed port for which there does not exist another sheet feed unit whose both sheet type and sheet width are the same, and creates a print job in a case where a user designates the first item, the print job including a command for the printing apparatus to automatically select a sheet feed unit from among the plurality of sheet feed units included in the first item.

A method for scheduling a depletion of a supply material in a printing system including a print engine capable of printing at a settable print velocity while using the supply material, a control unit for controlling a print job queue comprising at least one print job scheduled to be printed by means of a scheduling scheme while using the supply material, a supply material output holder for holding the supply material, and a user interface for interacting with a user of the printing system. The method includes determining a plurality of moments in time that the supply material output holder is full, and simultaneously scheduling for each determined moment in time of the plurality of moments in time a depletion event of emptying the supply material output holder in the scheduling scheme. The plurality of moments in time is determined by taking into account the total planned usage of the supply material according to print job specifications of the at least one print job scheduled in the print job queue and a capacity of the supply material output holder with respect to the properties of the supply material. Each of the determined moments in time is established on the basis of the settable print velocity of the printing system with respect to the at least one print job in the print job queue.

An example method involves analyzing a plurality of perturbations of a printing system over a period of time, calculating statistics corresponding to each of the plurality of the perturbations of the printing system, after the duration of the period of time, executing an enhancement process for the printing system based on the calculated statistics of each of the perturbations, and adjusting settings of the printing system based on results of the enhancement process.

A drawing unit configured to draw a print target content is instructed to draw a content and a predetermined element. Based on a notification from the drawing unit, which corresponds to the drawing instruction and has been made regardless of completion of drawing to the instruction, drawn data is acquired from the drawing unit. If the acquired data includes the predetermined element, a print apparatus is caused to execute printing based on the acquired data. If the acquired data includes no predetermined element, data is acquired from the drawing unit again without causing the print apparatus to execute printing based on the acquired data.

An example method of detecting device malfunctions at a subject device includes: obtaining a device event indicator representing an event detected at a device sensor of the subject device; obtaining an external event indicator representing an external event detected by an environmental sensor, the external event occurring external to the subject device; and identifying a device malfunction at the subject device based on the device event indicator and the external event indicator.

A terminal device as a prohibited relationship detection device detects presence or absence of a prohibited relationship, when change of a setting value related to a job condition is received, based on a PJL (Printer Job Language) index table to classify a plurality of configuration items of which input of setting values is received on the terminal device into a plurality of resolve tables, a plurality of resolve PJL tables showing relationship between setting values of which input is received on the terminal device and the PJL values which indicate the setting values of which input is received on the terminal device in the PJL, and an inter resolve PJL table prohibition table which shows a combination of setting values having a prohibited relationship, of which input is received on the terminal device.

An image forming system includes: a sheet feeder; an image former that forms an image on a paper sheet; a conveyor that conveys a paper sheet to a sheet ejection destination; a switcher that switches sheet ejection destinations; a reader that optically reads a paper sheet, and outputs a read image; an abnormal sheet detector that detects an abnormal paper sheet by analyzing the read image; a storage; a display; and a hardware processor that performs: ejection destination switch control to control the switcher to eject an abnormal paper sheet and a succeeding paper sheet to a second ejection destination different from a regular ejection destination; storage control, for each of the abnormal paper sheet and the succeeding paper sheet, to associate sheet information, the read image, and a stacking order with one another, and store them into the storage; and display control to cause the display to display them.
