To control an image forming apparatus using a service on a network, an information terminal performs two-factor authentication and acquires authentication information through the two-factor authentication so that the image forming apparatus accesses the service.

In a printing device, a supply portion is configured to convey a tape in its longitudinal direction. The tape includes: a plurality of labels arranged continuously in the longitudinal direction; and a plurality of storage elements provided on respective ones of the plurality of labels. A first storage element is provided on a first label and configured to store first authentication data. The second storage element is provided on a second label and configured to store second authentication data. A printing portion is configured to print on the plurality of labels. A controller is configured to perform: reading the first authentication data from the first storage element and the second authentication data from the second storage element by a reading portion; and determining whether the first authentication data is correlated to the second authentication data to meet an authentication condition.

In a printing system, a terminal device generates a plurality of pieces of print job data based on a data format list and transmit the generated print job data to a first multifunction machine, the first multifunction machine stores a plurality of pieces of received print job data, and performs printing based on print job data having the data format supported by the first multifunction machine itself when the first multifunction machine itself receives a print instruction from a user, and the second multifunction machine receives print job data having the data format supported by the second multifunction machine itself from the first multifunction machine when the second multifunction machine itself receives a print instruction from a user and performs printing based on the received print job data.

An image forming apparatus includes an operation device, one or more memories, and one or more processors that execute a set of instructions to receive a print job from an information processing apparatus, store the received print job in the one or more memories, control the operation device to display a list of print jobs stored in the one or more memories, register a print job included in the list in the image forming apparatus, based on a user instruction received by the operation device, and display an execution button for executing the registered print job in a function selection screen.

An image forming apparatus includes a processor configured to: transmit an inquiry as to whether or not printing of print data is allowed to an authenticated terminal when the print data are received from an external terminal, the authenticated terminal having an authority to perform printing and the external terminal being not registered in advance as the authenticated terminal; and make preparation to print the print data when a permission to print the print data is received from the authenticated terminal.

An information processing apparatus includes a processor configured to: accept a job that provides an instruction for execution of an apparatus function, the job being a delegable job to which a delegation specification is assigned, the delegation specification being used to delegate the execution to a user; and if an apparatus to be operated by the user to execute the delegable job satisfies a predetermined requirement, transmit the delegable job to the apparatus.

A terminal device may execute a first attempt process in which the terminal device attempts to communicate with a server on the Internet via a communication interface by using a specific LAN to which the terminal device is currently connected; and in a case where the attempt to communicate with the server is successful in the first attempt process, send connection information to a communication device different from the terminal device, the connection information being for connecting the communication device to the specific LAN, wherein in a case where a specific condition is fulfilled, the connection information is not sent to the communication device, the specific condition including a condition that the attempt to communicate with the server fails in the first attempt process.

A print control server that controls printing through an SNS includes a registration section configured to register, in association with each other, a first account that is an account of a user of the SNS and print setting information including designation information of a printer to be used for printing. The registration section issues a first password when accepting a designation of the first account and a designation of a second account that is an account of a user of the SNS and that is to be a share destination of a print setting, notifies the first account of the first password through the SNS, and registers, when a password posted on the SNS by the second account coincides with the first password, the print setting information registered in association with the first account also in association with the second account.

A printing apparatus includes a receiving unit which receives print data, an operating unit which receives a print instruction from a user, a display unit which displays a password entry screen for receiving a password entry from a user, and a printing unit which receives a print instruction from a user through the operating unit and prints print data without accepting a password through a password entry screen if a password added to the print data is matched with a fixed password and print data to be printed if a print instruction from a user is received through the operating unit, if the password added to the print data is matched with the fixed password, and if the password received through a password entry screen is matched with the password added to the print data.

In response to receiving an instruction operation in a receiving process, a processor executes an apparatus-side preparing process including an issuance requesting process of transmitting issuance requesting information to a server through a communicator, the issuance requesting information being information for requesting issuance of authentication information indicative of authority to perform data communication with a service providing apparatus, the instruction operation being a user operation of instructing execution of a preparing process for connecting the image forming apparatus to the service providing apparatus, a storage-instruction receiving process of receiving storage instructing information from the server through the communicator, the storage instructing information being information including the authentication information issued by the service providing apparatus, and a first near-field transmitting process of, in response to approach of the card to the first near-field communicator, transmitting the authentication information included in the storage instructing information to a card through a near-field communicator.
