An image processing service system includes an operation request accepting unit, a setting accepting unit, a payment control unit, and an operation execution control unit. The operation request accepting unit accepts an operation request for an image processing apparatus through a chat between a user and a chatbot participating in a chat service on a chat board provided by the service. The setting accepting unit accepts a setting for an operation of the image processing apparatus requested by the operation request. The payment control unit makes a payment for the operation of the image processing apparatus requested by the operation request through an electronic payment system available on the chat service. The operation execution control unit controls the image processing apparatus to execute the operation requested by the operation request after the setting is accepted by the setting accepting unit and the payment is made by the payment control unit.

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.

A non-transitory computer-readable storage medium stores computer-readable instructions that are executable by a processor of an information processing device and compatible with a printer connected with the information processing device. The instructions support a general-purpose printing program incorporated in an operating system of the information processing device. The general-purpose printing program is configured to handle data for displaying a print setting screen on the information processing device. The instructions, when executed by the processor, cause the information processing device to, after print settings are changed via the print setting screen, determine whether the print settings are proper based on capability information of the printer, when determining that the print settings include improper settings, generate first notification data indicating that the print settings are improper, and provide the first notification data to the general-purpose printing program, thereby enabling the first notification data to be displayed on the print setting 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 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.

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.

An image forming apparatus has an office direct print function, and when a non-installed font that is not installed in the image forming apparatus is included in application data, a font substitution guidance screen is displayed on a display. A drop-down list that is an operator for selecting a substitute font is provided in the font substitution guidance screen, whereby a user can arbitrarily select a substitute font. The font substitution guidance screen displays also a sample character group having a typeface according to the selected substitute font.

An information processing apparatus receives, from an image forming apparatus, setting values of a first setting item including a first setting value, setting values of a second setting item including a second setting value and a selected first combination without receiving a second combination, causes a display to display a first object for selecting one of the received setting values of the first setting item and a second object for selecting one of the received setting values of the second setting item, and restricts, based on the received first combination, setting a combination of the first setting value and the second setting value among combinations of setting values set by the first object and the second object.

A control method of an information processing apparatus on which an expansion application configured to expand a function of print data generation software configured to generate print data runs, is provided. The control method comprises obtaining attribute data on a printing apparatus, the attribute data being output from the printing apparatus, obtaining data indicating a print function, and adding information related to a specific function based on attribute information included in the obtained attribute data if information indicating the specific function is not included in the obtained data indicating the print function. A setting screen including a setting item of the specific function is displayed based on the added information related to the specific function.

A supporting program is executable by a controller of an information processing apparatus and corresponds to a printer connected to the information processing apparatus. The supporting program causes the information processing apparatus to perform processing intermediate image data in accordance with a print parameter received in a print parameter editing process, displaying an image indicated by the processed inter mediate image data on a print preview screen. The information processing apparatus does not restrict printing when print continuation is instructed, while restricting the printing when re-edit or print cancel is instructed.

An information processing apparatus includes a printer driver configured to generate a print command compliant with a predetermined printing protocol based on print data obtained from a data generation application, one or more extension modules configured to generate a print command compliant with another printing protocol different from the predetermined printing protocol, a storage unit configured to store information associating the one or more extension modules to be used for generating the print command compliant with said another printing protocol with the printer driver, and an output unit configured to output the print command compliant with said another printing protocol, the print command being obtained through processing of the print data obtained by the printer driver, and the processing being performed by the one or more modules indicated by the information.
