Abstract: A non-transitory recording medium, an information processing apparatus, and a print control method. The non-transitory recording medium storing instructions which, when executed by one or more processors of an information processing apparatus, cause the processors to determine whether a setting screen for receiving setting information related to a print process can be displayed on a display after the print process is started, display on the display the setting screen when the setting screen can be displayed and control the print process using the setting information received on the setting screen.

Abstract: An image display device includes: an image display unit which includes a display panel switchable between an image display mode in which an image is displayed and a transmissive mode in which the display panel is in a transmissive state where an object behind the image display unit is visible in a front view of the display panel; a controller which controls an operation of the display panel; and a lower shelf board which is a holding member. The lower shelf board is disposed projecting rearward from a rear surface of the image display unit and holds the controller in a housed state.

Abstract: An information processing apparatus, system, and a non-transitory recording medium storing instructions for executing an information processing method. The information processing system includes the information processing apparatus with one or more printer drivers installed and an image forming apparatus connected to the information processing apparatus to perform bidirectional communication with the image forming apparatus in response to a request from at least one of the printer drivers, by setting control information in a storage area corresponding to the printer driver and requesting a communication control program to perform the bidirectional communication with the image forming apparatus based on a control information set for the printer driver.

Abstract: An information processing apparatus includes a memory and circuitry. The circuitry is configured to send a request for status information to an image processing apparatus. The status information indicates a status of the image processing apparatus. The circuitry is configured to acquire the status information from the image processing apparatus in response to the request. The circuitry is configured to store, in the memory, the status information acquired, in association with identification information. The circuitry is configured to retrieve the identification information from the memory when a standby time elapses. The circuitry is configured to determine whether the identification information retrieved satisfies a certain condition. The circuitry is configured to display, on a display, a screen indicating the status of the image processing apparatus based on the status information acquired, based on a determination that the identification information retrieved satisfies the certain condition.

Abstract: A print processing system includes a bidirectional communication part that carries out bidirectional communication with an information processing apparatus and an image processing apparatus; a command generation part that generates, based on a request received by the bidirectional communication part from the information processing apparatus, a request command to be transmitted to the image processing apparatus, depending on a print protocol of the image processing apparatus; and a response conversion part that converts a response that corresponds to the request command and has been received by the bidirectional communication part from the image processing apparatus, into a response that is to be transmitted to the information processing apparatus, and has a form that does not depend on print protocols.

Abstract: A printer driver that cooperates with a plug-in that can be added thereto and removed therefrom includes: a determining unit that determines whether or not the plug-in is used at predetermined timing at which a printing process is hooked; a reading unit that reads the plug-in that is determined by the determining unit; and a calling unit that calls the plug-in read by the reading unit.
