A non-transitory storage medium stores a program set readable by a computer of a first information processing apparatus. The program set including a first program and a second program. The first program causes the first information processing apparatus to start the second program, and register the started second program, as a virtual scanner, in an operating system of the first information processing apparatus. The second program causes the first information processing apparatus to transmit a scan command of the first protocol to the external scanner, and receive a read result from the external scanner by the first protocol through the communication interface. The external scanner reads a document in response to receipt of the scan command transmitted from the information processing apparatus.

A printing device has a print unit for printing on roll paper; a wireless communication unit for communicating wirelessly with a paired control device; and a controller for receiving print data by wireless communication from the control device, and controlling the print unit based on the received print data. When changing from a pairing-disabled mode to a pairing-enabled mode, the controller controls the print unit to print pairing-related information on roll paper, does not process pairing in the pairing-disabled mode, and processes pairing when a pairing request is received in the pairing-enabled mode.

An information processing apparatus capable of reliably switching a session. An IP fax as an information processing apparatus is connected to another IP fax. The IP fax establishes an audio session with the other IP fax. After establishing the audio session, the IP fax receives capability information indicating capabilities of the other IP fax therefrom. After receiving the capability information, the IP fax requests the other IP fax to switch the audio session to a T.38 session. Then, the IP fax switches the audio session to the T.38 session.

A printing device has a print unit for printing on roll paper; a wireless communication unit for communicating wirelessly with a paired control device; and a controller for receiving print data by wireless communication from the control device, and controlling the print unit based on the received print data. When changing from a pairing-disabled mode to a pairing-enabled mode, the controller controls the print unit to print pairing-related information on roll paper, does not process pairing in the pairing-disabled mode, and processes pairing when a pairing request is received in the pairing-enabled mode.

There is provided a mobile terminal. A near field communication unit performs near field communication. A wireless communication unit performs wireless communication that differs in a communication protocol from the near field communication. An acquiring unit, when a connection with an image forming apparatus is established through the near field communication unit, acquires identification information of the image forming apparatus from the image forming apparatus through the near field communication unit. A print instructing unit, when the acquiring unit acquires the identification information, but print completion information is not recorded in a storage unit, transmits print instruction information to instruct printing of data to the image forming apparatus of the identification information through the wireless communication unit or the near field communication unit, and records the print completion information in the storage unit.

A non-transitory storage medium stores a program set readable by a computer of a first information processing apparatus. The program set including a first program and a second program. The first program causes the first information processing apparatus to start the second program, and register the started second program, as a virtual scanner, in an operating system of the first information processing apparatus. The second program causes the first information processing apparatus to transmit a scan command of the first protocol to the external scanner, and receive a read result from the external scanner by the first protocol through the communication interface. The external scanner reads a document in response to receipt of the scan command transmitted from the information processing apparatus.

An information processing apparatus that positively notifies a notification destination of information to be notified even if a communication protocol is changed before notifying storage of stored data. A notification setting processing section of a document storage notification application sets a protocol for accessing the stored document data from a computer via a network. When document data is stored in a HDD, a mail transmission processing section notifies the computer of storage location information on the document data for accessing the data according to the set protocol. If the set protocol is changed before the storage location information is notified to the computer, a control section causes the mail transmission processing section to notify the computer of storage location information for causing the document data to be accessed using the changed protocol.
