A post processing apparatus is used effectively, an execution waiting time of a print job due to moving of a self-travelling post processing apparatus is shortened, and a total printing time is shortened, whereby productivity is increased. In an image forming system which includes a self-travelling post processing apparatus being separably connected to an image forming apparatus, when receiving a plurality of print jobs including both a print job which performs the post processing by the post processing apparatus and a print job which does not perform post processing, an execution order of the plurality of print jobs is changed in accordance with a connecting state of the post processing apparatus to the image forming apparatus.

A printer-verifier is provided for printing and verifying a printed indicium. Printer-verifier includes imaging module for capturing image of printed indicium on print media, memory communicatively coupled to imaging module and configured to store print quality verification program, and processor communicatively coupled to memory. Processor is configured by print quality verification program to evaluate print quality of printed indicium, determine if print quality meets print quality standard, reject printed indicium on print media as rejected printed media when print quality does not meet print quality standard, and one of output location-specific feedback about rejected printed media or send a command signal to cutting device to destroy rejected printed media. Location-specific feedback is in same language as language associated with printer-verifier. A printer and methods for verifying the printed indicium are also provided.

An image forming system includes an image forming apparatus configured to form an image on a sheet, a plurality of accessory apparatuses arranged side by side along a conveyance direction of the sheet, and a base station configured to wirelessly communicate with the image forming apparatus and the plurality of accessory apparatuses. The image forming apparatus includes one or more controllers configured to function as (i) a unit configured to acquire, from the base station, information that the base station acquires by wirelessly communicating with the plurality of accessory apparatuses, and (ii) a unit configured to output screen information for registering information about an arrangement order of the plurality of accessory apparatuses, based on the information acquired from the base station.

An image forming apparatus includes an image forming unit that outputs an image to a transfer medium on the basis of a job and a control unit that controls the image forming unit. The control unit is capable of outputting all sheets and outputting designated sheets in outputting the job and, when outputting the designated sheets, changes output control content according to whether the designated sheets are output as sheets for replacement media.

A printing apparatus system, comprising: a printing apparatus; and connection devices connected to the printing apparatus in multistage, wherein a device side controller is configured to: execute an authentication process in cooperation with an apparatus side controller when a signal is input thereto, the signal corresponding to a start command signal output from the printing apparatus and input to an electric resistance; and execute a level process where a voltage level of the start command signal passed the electric resistance is set to be higher than or equal to a predetermined level when the authentication process is finished, wherein the apparatus side controller is configured to store identification information assigned to each of the connection devices and number-of-stage information indicating, for each of the connection devices, which stage a connection device associated with the identification information is connected to, wherein the identification information is associated with the number-of-stage information.

An image forming apparatus includes a communication interface, an image forming unit, a plurality of sheet feeders, and a motor configured to selectively apply a drive force any of the sheet feeders. A transmission assembly switches transmission to any one of the sheet feeders. A controller receives preceding data from the communication interface, and, in response, controls the transmission assembly to initiate a switch of the transmission of the drive force to a standard sheet feeder among the plurality of the sheet feeders. In response to receipt control data received after the preceding data, the controller controls the image forming unit, motor, and transmission assembly to form an image on the sheet based on an image forming condition included in the control data.

An image forming system that is capable of preventing obstruction of transmission of a packet to an information processing apparatus from a USB device supporting USBNW due to the shift to the sleep mode. The image forming system includes an information processing apparatus, an image forming apparatus with a sleep mode, and a USB device that is connected to the information processing apparatus through the image forming apparatus and is controlled by the information processing apparatus. The image forming apparatus includes a first determination unit that determines whether the USB device supports USBNW, a second determination unit that determines whether a packet received from the information processing apparatus is processed by a module supporting USBNW, and a control unit that prohibits the image forming apparatus from shifting to the sleep mode when the USB device supports USBNW and when the packet is processed by the module supporting USBNW.

A system for controlling an operation of feeding recording media from a plurality of physical medium containers of an output apparatus includes at least one memory to store output-related media/container information including logical information, property information of the recording media, and information of the plurality of physical medium containers by associating the logical information and the property information of the recording media, and associating the logical information and the information of the plurality of physical medium containers, and circuitry configured to generate an output instruction including logical information, extract the logical information from the output instruction, and identify one or more physical medium containers each containing a specific recording medium to be used in performing an image forming operation by referring the property information of the recording media and the information of the plurality of physical medium containers each associated with the extracted logical information in the memory.

At least one embodiment of a post-processing apparatus performs post-processing on a product printed by a printing apparatus, and transmits a command for a temporary stop of print processing for a first job and information indicating a reason for the temporary stop to the printing apparatus. At least one embodiment of the printing apparatus receives the command for the temporary stop of the print processing for the first job and the information indicating the reason for the temporary stop, stops the print processing for the first job according to the command for the temporary stop, and acquires a period of time during which the temporary stop continues based on the received information indicating the reason for the temporary stop.
