A print device for automatically printing a document file from a portable memory device may include a port, a print engine, and a processing device. The processing device may detect that a portable memory device has become communicatively connected to the port, then access a print history from a data store and retrieve a print instruction, use the print history to determine that a document file in a designated folder of the portable memory device has not been printed, and automatically print the document file using the print engine based on the print instruction. After printing, the device may further transmit a communication to the data store to update the print history to reflect that the document file is printed. The print device may be capable of detecting an interruption and allowing a user to resume the print job later on the same print device or on another device.

An information processing apparatus includes a volatile memory that stores data, a controller that controls an operation of a device, an interface that temporarily stores data input from the device, a writing unit that controls writing of the data on the volatile memory, a first communication pathway that connects the interface to the writing unit and is used to transmit the data acquired by the interface to the volatile memory and to transfer the data written on the volatile memory, a second communication pathway that connects the interface to the writing unit and does not share a route with the first communication pathway, and a switching unit that switches a communication path used to transmit data from the interface to the volatile memory from the first communication pathway to the second communication pathway if the interface has received image data from the device.

A print recording system, including: at least one print recording device; and a computer system that includes a database storing a plurality of print setting information items and is capable of sending and receiving data with respect to the print recording device. The computer system searches the print setting information corresponding to a search condition that is input from the database in accordance with the search condition, repeats the search in accordance with a new search condition when the print setting information does not match the search condition, and sends the print setting information obtained by the search or the repeated search to the print recording device to set the print recording device.

A tandem type image forming system includes a first image forming apparatus, and a second image forming apparatus connected in series to the first image forming apparatus and located on a downstream side in a sheet conveyance direction with respect to the first image forming apparatus. The tandem type image forming system has a controller which shortens a second sheet interval when conveying a plurality of consecutive sheets from the first image forming apparatus to the second image forming apparatus than a first sheet interval when conveying the plurality of consecutive sheets from the second image forming apparatus to a post processing apparatus connected to the second image forming apparatus.

A display includes a display unit, an image sensor that takes an image of a predetermined area and outputs the taken image, and a hardware processor that detects the marker in the taken image, generates differential color information between color data of the marker in the taken image and color data of the marker in the print image data, displays a virtual object which reproduces the print image data in the display unit, sets an object adjustment value for adjusting a color tone of the virtual object displayed on the display unit based on the differential color information, and calculates a print adjustment value for adjusting a color tone reproduced by the image forming apparatus based on the object adjustment value.

An image printing apparatus including a communication interface, a printer, a user interface including an operation panel, a controller configured to control the printer and the user interface is provided. The controller is configured to receive preliminary data sent from an information processing apparatus through the communication interface; control the printer to perform a warm-up action; receive job data including image data through the communication interface; control the user interface to perform a receipt-notification and control the printer to start printing based on the image data; during a period from the receipt of the preliminary data until start of receiving the job data, withhold from accepting a cancellation command sent in response to user entering a cancellation operation; and after the start of receiving the job data, accept the cancellation command and cancel printing of the image based on the job data associated with to the entered cancellation command.
