Image forming apparatus and image forming system

An image forming apparatus, comprising:

• a communication interface;
• an image forming device;
• a user interface;
• a memory;
• and
• a controller configured to:
• when print job data constituting a print job is received through the communication interface, and on condition that the received print job data indicates a first parameter being applied to the print job, execute a print-in-progress screen displaying process, in which the controller controls the user interface to display a print-in-progress screen including a specific object while the image forming device is in progress of image printing for the print job;
• and
• in response to an operation to the specific object in the print-in-progress screen through the user interface rendered before completion of the image printing for the print job, execute a print resuming process, in which the controller aborts the image printing in compliance with the first parameter and controls the image forming device to print images for the print job in compliance with a second parameter.

An image forming system, comprising:

• an image forming apparatus comprising a first communication interface and a first user interface;
• and
• an external device comprising a second communication interface and a second user interface,
• wherein the external device is configured to transmit reservable print job data constituting a reservable print job through the second communication interface to the image forming apparatus, the reservable print job being a print job to be saved temporarily in a memory in the image forming apparatus without being used for image printing by an image forming device in the image forming apparatus directly upon reception through the first communication interface but to be used by the image forming device for image printing in response to an executing instructing operation accepted in the image forming apparatus through the first user interface;
• wherein the image forming apparatus is configured to, in response to receiving of the reservable print job data from the external device through the first communication interface, display a print standby screen in the first user interface, the first user interface displaying the print standby screen being acceptable of an execution instructing operation for the reservable print job, the image forming apparatus being configured to, on condition that the received reservable print job data indicates a first parameter being applied to the received reservable print job, control the first user interface to further display a specific object in the print standby screen;
• and
• wherein the image forming apparatus is configured to, in response to the execution instructing operation being rendered through the first user interface without accompanying an operation to the specific object in the print standby screen, control the image forming device to print images for the reservable print job in compliance with the first parameter, the image forming apparatus being configured to, in response to the operation to the specific object in the print standby screen and the execution instructing operation are rendered through the first user interface, control the image forming device to print the images for the reservable print job in compliance with a second parameter.

An image forming system, comprising:

• an image forming apparatus comprising a first communication interface and a first user interface;
• and
• an external device comprising a second communication interface and a second user interface,
• wherein the external device is configured to transmit print job data constituting a print job through the second communication interface to the image forming apparatus;
• wherein the image forming apparatus is configured to:
• when the print job data from the external device is received through the first communication interface, and on condition that the received print job data indicates a first parameter being applied to the received reservable print job, display a print-in-progress screen including a specific object in the first user interface while the image forming device is in progress of image printing for the print job;
• and
• in response to an operation to the specific object in the print-in-progress screen through the first user interface rendered before completion of the image printing for the print job, abort the image printing in compliance with the first parameter and control the image forming device to print images for the print job in compliance with a second parameter.
