Information apparatus and application software supporting printing over air or network are herein disclosed and enabled. The information apparatus may include one or more software components that include (1) a discovery component to discover a supported printer in a local area network (LAN) and to receive device information related to the printer (e.g., capability, language or format supported, identification) from the printer, and (2) a printing component to generate or obtain print data based on the device information received and to transmit the print data to the discovered printer. After establishing the connection to the LAN, application software (e.g., Internet browser, email, photos, documents) in the information apparatus may print digital content by using the discovery component to discover the printer in the LAN, and may use the printing component to obtain and transmit print data in a form that is acceptable to the printer for printing the digital content.

An information processing apparatus includes: an operating unit capable of recognizing a peripheral apparatus. The operating unit includes: a first recognizing unit configured to recognize, when a peripheral apparatus is connected to the operating unit and identification information about the connected peripheral apparatus is included in peripheral apparatus information including predetermined identification information, the connected peripheral apparatus as a first peripheral apparatus; and a second recognizing unit configured to recognize, when a peripheral apparatus is connected to the operating unit and the identification information about the connected peripheral apparatus is not included in the peripheral apparatus information, the connected peripheral apparatus as a second peripheral apparatus.

A terminal device as a prohibited relationship detection device detects presence or absence of a prohibited relationship, when change of a setting value related to a job condition is received, based on a PJL (Printer Job Language) index table to classify a plurality of configuration items of which input of setting values is received on the terminal device into a plurality of resolve tables, a plurality of resolve PJL tables showing relationship between setting values of which input is received on the terminal device and the PJL values which indicate the setting values of which input is received on the terminal device in the PJL, and an inter resolve PJL table prohibition table which shows a combination of setting values having a prohibited relationship, of which input is received on the terminal device.

A non-transitory computer-readable storage medium stores a support program for an information processing device connectable to a printer. The information processing device includes: a display; a computer; and a memory. The memory stores an operating system in which a general-purpose printing program corresponding to the printer and supported by the support program is embedded. The general-purpose printing program is configured to manage data for displaying a print settings screen on the display. The support program, when executed by the computer, causes the information processing device to perform: when a connection error that a connection between the information processing device and the printer has failed is confirmed: generating; and transferring. The generating generates notification data indicating a notification content for notifying a user of the connection error. The transferring transfers the notification data to display the notification content based on the notification data on the print settings screen.

A non-transitory computer-readable storage medium stores a support program for an information processing device connectable to a printer. The information processing device includes: a display; a computer; and a memory. The memory stores an operating system in which a general-purpose printing program corresponding to the printer and supported by the support program is embedded. The general-purpose printing program is configured to manage data for displaying a print settings screen on the display. The support program, when executed by the computer, causes the information processing device to perform: when a request is issued from the general-purpose printing program in response to the printer being selected: acquiring; generating; and transferring. The acquiring acquires status information indicating a status of the printer. The generating generates notification data indicating a notification content to be provided to a user. The transferring transfers the notification data to display the notification content on the print settings screen.

A print data generating device is configured to generate print data for creating a printed medium by printing a target image on a heat-sensitive medium with a printing device. The printing device includes a thermal head having a heating element. The heat-sensitive medium includes: a base material; and a heat-sensitive layer. The base material has a transparency. The heat-sensitive layer is provided over one surface of the base material and is configured to develop a first color when heated to a first temperature or higher. The printing device is configured to control the heating element according to the print data to heat the heat-sensitive medium. The print data generating device includes a controller. The controller is configured to perform: (a) determining a condition of a background area on which the heat-sensitive medium is to be superimposed; and (b) generating the print data in accordance with the condition determined in (a).

An information processing apparatus is capable of communicating via a universal serial bus (USB) cable with a USB host device configured to transmit a first control transfer command at a start of communication. The information processing apparatus includes one or more controllers configured to function as a unit configured to acquire and hold predetermined data in response to having received the first control transfer command from the USB host device and a unit configured to transmit the held predetermined data to the USB host device on the basis of having received a second control transfer command from the USB host device.

An image processing apparatus of one embodiment includes an image processing unit and a controller. The controller receives biometric information for a user for a logon operation and re-orders user record entries in a table when a predetermined condition occurs. Each record entry in the table includes reference biometric information in association with user information. The re-ordering of the entries is based on user information stored in the user record entries. After the re-ordering of the user record entries in the table, the controller performs an authentication operation that includes comparing the received biometric information to reference biometric information in the re-ordered user record entries of the table until a match is determined.
