Aspects of the disclosure provide an electronic device comprising a controller. The controller to determine a volume of print fluid in a first tank of the electronic device, monitor current printing conditions of the electronic device disposing print fluid on a substrate, determine, based on the volume of print fluid and the current printing conditions, whether an adverse printing condition exists, responsive to the volume of print fluid being less than a threshold and the adverse printing condition not existing, control a pump to refill the first tank from a second tank at a flow rate determined at least partially according to the determined volume, and responsive to the volume of print fluid being less than the threshold and the adverse printing condition existing, control the pump to refill the first tank from the second tank at a default flow rate determined independent of the determined volume.

A cooling device includes a cooling member to absorb heat from a conveyed sheet and a plurality of cooling units to cool the cooling member. Each of the cooling units includes a coolant channel through which a coolant flows and a liquid-cooling device configured to cool the coolant that flows in the coolant channel. The coolant channels are disposed on or inside the cooling member and arranged side by side in a sheet conveyance direction. The coolant channels includes a downstream coolant channel being downstream from at least one of the plurality of coolant channels in the sheet conveyance direction, and an upstream coolant channel being upstream from the downstream coolant channel in the sheet conveyance direction. One of the liquid-cooling devices coupled to the downstream coolant channel has a cooling capacity higher than a cooling capacity of another of the liquid-cooling devices coupled to the upstream coolant channel.

A multifunction peripheral includes means for receiving a request from a multifunction peripheral management service, means for enabling a function in the multifunction peripheral in accordance with the request, and means for transmitting a result of the request as a response to the multifunction peripheral management service.

An image forming system includes an image forming and a server. The image forming device includes a controller configured to operate in accordance with a normal mode or a contract mode. The server is configured to perform transmitting, to the image forming device, an operation mode changing instruction to set an operation mode of the controller to one of a normal mode or a contract mode in accordance with an operation mode changing request. The image forming device is configured to set the operation mode in accordance with the operation mode setting instruction.

A printer includes a vertical type main body accommodating a printing portion that prints an image onto a print medium transported along a vertically oriented printing path, including an outlet through which the print medium is discharged. A depth of the main body may be less than a width and a height of the main body. The printer may further include a stand supporting the main body such that the main body is rotatable forward and backward, a discharge guide mounted to the main body to be rotatable in a vertical direction and guiding the print medium discharged from the outlet forward, and an elastic member applying an elastic force to the discharge guide in a direction in which the discharge guide is rotated upward.
