An inkjet recording device includes a first tray for supporting sheets, a storage body for storing ink, a head for ejecting ink, a platen positioned between the head and the first tray, and a first guide member. The platen is configured to support a first surface of the sheet conveyed rearward at a position below the head. The first guide member is positioned frontward of the head and has a first curved surface configured to guide the first surface of the sheet conveyed from the first tray toward the platen. The first guide member has a portion arranged in alignment with the storage body in a widthwise direction perpendicular to an up-down direction and a front-rear direction. The first guide member has a portion positioned at the same height as the storage body in the up-down direction.

An image forming apparatus has a main body housing, a network interface for connecting to a network, a cartridge mountable to the main body housing and having a material or a component to be used for image formation in the image forming apparatus and a memory that stores contract information for permitting use of the cartridge in the image forming apparatus set to a contract mode, a communication unit for performing communication with using a mobile network different from the network, and a controller. The controller acquires the contract information from the memory, in a state where the cartridge is mounted to the main body housing, permits printing in the image forming apparatus using the cartridge based on the contract information, and transmits information about the image forming apparatus or the cartridge regarding the contract mode to a communication apparatus via the communication unit.

A printing system includes a printing mechanism. The printing mechanism is configured to perform printing. The printing system stores a plurality of print jobs in a storage, and receives selections of two or more print jobs to be executed as two or more target jobs from among the plurality of print jobs stored in the storage. The printing system determines a total fee to be charged for executing the two or more target jobs, and performs a settlement related process related to settlement of the determined total fee. The printing system executes the two or more target jobs to print images by using the printing mechanism in response to completion of settlement of the total fee.

A printing system includes: a printer including a controller; and a contract processing server. The controller is configured to perform: determining, in response to receiving from an external device a print job including print data representing an image, whether authority information indicating an authority to print the image has been issued; and transmitting, in response to determining that the authority information has been issued, to the contract processing server an inquiry for determining whether the authority information is valid. The contract processing server is configured to perform: transmitting, in response to receiving the inquiry, a response to the controller. The controller is configured to further perform: determining, in response to receiving the response, whether the authority information is valid on the basis of the received response; and printing, in response to determining that the authority information is valid, the image on a print medium by controlling the printer.

A printing system includes: a printing device; and a data processing server. A first controller of the printing device is configured to perform: a reading process to read a reading target to generate image data; a determination process to determine whether to transmit the image data to the data processing server according to at least one of available capacity information and capacity-related information; and a data transmission process to transmit the image data to the data processing server. A second controller of the data processing server is configured to perform: a payment-related process related to a fee payment for printing based on the image data. The first controller is configured to further perform, after the fee payment is completed: an acquisition process to acquire print data corresponding to the image data; and a printing process to form an image corresponding to the print data on a printing medium.

The first controller is configured to further perform: an acquisition process to acquire print data corresponding to the image data after the payment of the fee is completed; and a printing process to form the image corresponding to the print data on a printing medium.

A printing system includes a printing device and a data processing server. The printing device includes a first controller. The data processing server includes a second controller. The first controller acquires a print job from an external device and transmits the print job to the server. The second controller receives the print job and stores the print job in a server memory. The first controller receives designation of the print job subject to printing and transmits a print request for printing the print job subject to printing to the server. After a fee payment approval to approve a payment for execution of the designated print job is transmitted, the second controller transmits to the printing device the print job. The first controller receives the print job and performs printing the print job on a print medium by controlling a printing member.

A printer includes a printing unit that ejects an ink from an inkjet head onto a medium, and a mist suction unit that suctions mist of the ink. The printing unit includes a first inkjet head, and a second inkjet head provided downstream of the first inkjet head in a transport direction of the medium. The mist suction unit includes a first mist suction device provided between the first inkjet head and the second inkjet head in the transport direction, a second mist suction device provided downstream of the second inkjet head in the transport direction, a first flow path coupling a blower and the first mist suction device, and a second flow path coupling the blower and the second mist suction device. A suction force of the second mist suction device is stronger than a suction force of the first mist suction device.

An MFP 1 includes an image forming unit 4 which forms an image on a sheet S1, a USB interface 12 which is to be connected to a PC 101 via a USB and receives a preceding command described in accordance with a control transfer protocol that is a transfer scheme of USB connection, and a CPU 91 which executes a preparation operation of the image forming unit 4, in response to receiving the preceding command by the USB interface 12. The preceding command is described to instruct the preparation operation of the image forming unit 4.
