A communication device may include a controller. The controller may be configured to, in a case where a process executing instruction is sent to a notification server from a terminal device, receive a process executing notification from the notification server, and in a case where the process executing notification is received from the notification server, execute a predetermined process. The process executing notification may be received by operating in parallel in a first mode and a second mode. In the first mode, the process executing notification may be received by sending a polling signal to the notification server. In the second mode, the process executing notification may be received by establishing a connection of server-push type between the communication device and the notification server.

A print control device 31 connected to a host 20 and a printer 32 has a print data receiving unit 81 that receives print data written in markup language from the host 20, a command generating unit 82 that adds an initialization command before the print data and generates a print instruction command, and a command transmission unit 83 that transmits the generated print instruction command to the printer 32.

An image processing system includes a server to control a plurality of processes performable in the image processing system, a first image forming apparatus communicable with the server, and a second image forming apparatus communicable with the server. The server includes a first memory to store first image processing data, and a first processor to generate first image drawing information based on the first image processing data. The second image forming apparatus includes a second memory to store second image processing data, a second processor to generate second image drawing information based on the second image processing data, and a print engine to perform the image forming operation of the second image forming apparatus based on the second image drawing information.

A display screen generation apparatus includes: an acquisition portion acquiring for each of a plurality of print products produced through a plurality of processes, progress of the processes; and a display portion generating a display screen that displays for each of the plurality of print products, the process waiting to be executed, the process being executed, the process already executed, and the process not intended to be executed in a distinguishable manner from each other.

When a job for executing both of a one-sided printing and a two-sided printing, the lowering of the productivity is suppressed and an output result a user desires is output.

A method for a printer including a transport device including an endless transport belt supported on a pair of support rollers, which between them define a medium support plane, over which medium support plane a print station is provided. The method includes transporting in parallel a plurality of individual print media perpendicular to a scanning direction of the print station on the medium support plane, the print media having different dimensions; determining positions of the individual print media based on the determined positions; and jetting marking material for forming a designated image specific for each print medium on each respective print medium. The above steps are repeated such that print media are printed in a plurality of parallel lanes on the medium support plane perpendicular to the scanning direction. The printer is provided with a plurality of guiding bars extending in the transport direction and positioned at a side of at least one lane of the plurality of parallel lanes in order to guide the individual print media into one of the plurality of parallel lanes. The printer includes a print controller for controlling the print process for a digital image to be printed, the print controller including two print queues for receiving digital images to be printed by the printer. It is established if the digital image requires to be right aligned or left aligned along a guiding bar. In case of a required left alignment, the digital image is added to a first print queue of the two print queues. In case of a required right alignment, the digital image is added to a second print queue of the two print queues.

A terminal device includes an operation interface, a short-range wireless communication interface, and a processor. The terminal device receives a designating operation of designating a model of an image processing device and a setting operation of setting an execution condition to perform an imaging process. After establishing a short-range wireless communication with the image processing device, the terminal device determines whether a model of the image processing device coincides with a designated model. When the two models coincide with each other, an execution instruction is transmitted to the image processing device.

Disclosed is an image forming apparatus. The present image forming apparatus comprises: an input unit for receiving a scanning option; a communication unit for transmitting the received scanning option to another image forming apparatus; a scanning unit for scanning a first document according to the scanning option and generating first scanned data; and a control unit for receiving second scanned data in which a second document is scanned according to the scanning option in another image forming apparatus, and combining the first scanned data and the second scanned data.

The invention includes an arrangement determiner that determines an arrangement of a plurality of images, a rendering processor that performs rendering on the plurality of images in accordance with a result of detection processing for detecting an off line, on which none of the images are present across a target range in a second direction perpendicular to a first direction in which a print medium is transported, in the target range including the plurality of images arranged in accordance with a determination performed by the arrangement determiner, and a halftone processor that performs halftone processing on the images on which the rendering has been performed and outputs to the printing apparatus the images on which the halftone processing has been performed.

An image forming system in which distributed processing of a job is performed by a plurality of image forming apparatuses and each of the image forming apparatuses inspects an output image formed on paper by distributed processing. Among the image forming apparatuses which perform distributed processing, one or more image forming apparatuses generate data for abnormal image detection which is required to inspect the output image in the image forming apparatuses to perform the distributed processing.
