Abstract:
A management device may be connected with first and second devices via a network. The management device may acquire “m” programs that are to be updated in the first device and “n” programs that are to be updated in the second device, from a server. Each of “m” and “n” may be an integer greater than or equal to 2, the “m” programs may include first and second programs, and the “n” programs may include a third and a fourth programs. The management device may transmit the first program to the first device and transmit the third program to the second device. The management device may, after completion of the transmitting the first program and the third program, transmit the second program to the first device and transmit the fourth program to the second device.
Abstract:
A communication apparatus may include a reception portion, a decision portion, and a transmission portion. The reception portion may receive a first data request transmitted through a first security level communication, and a second data request transmitted through a second security level communication, the second security level being more secure than the first security level. The decision portion may decide whether a specific data request is the first data request or the second data request. The transmission portion may transmit a specific data to an apparatus that is a transmission source of the specific data request if the specific data request is the second data request, and may transmit different data to the apparatus if the specific data request is the first data request. The different data contains display information for causing the apparatus to retransmit the specific data request through the second security level communication.
Abstract:
A management device may be connected with a specific device via a network, and cause the specific device to update a plurality of programs. The management device may transmit a first program of the plurality of programs by using an IP address as a transmission destination. The management device may confirm whether the IP address of the specific device has changed since transmitting the first program by utilizing identification information for identifying the specific device. The management device may transmit a second program of the plurality of programs to the specific device by using the IP address when confirming that the IP address has not changed, or by using a changed IP address when confirming that the IP address has changed.
Abstract:
A printer may judge whether a first type of communication with the print mediation server. The printer may execute the first type of communication and receive a predetermined notification in a case where it is judged that the first type of communication is executable. The printer may, (A) execute, when the predetermined notification is received a second type of communication so as to acquire specific address information, in the case where being judged that the first type of communication is executable and (B) execute, even if the predetermined notification is not received, the second type of communication at a predetermined timing so as to acquire the specific address information in a case where it is judged that the first type of communication is not executable. The printer may acquire the specific print data and print an image represented by the specific print data.

Abstract:
An image projection device which can freely set access information to other devices which are connected to a communication network and exhibits excellent user-friendliness and secrecy is provided. An image projection device acquires image data via the communication network and projects an image based on the image data. The image projection device includes: a receiving unit which receives an E-mail transmitted from another device which is connected to the communication network and containing information on the image data; a content analyzing unit which analyzes a content of the E-mail received by the receiving unit; and an image data acquiring unit which acquires the image data via the communication network based on an analysis result obtained by the content analyzing unit.

Abstract:
A printer may receive a predetermined notification from a print mediation server. The predetermined notification may be a notification to be sent to the printer by the print mediation server when the print mediation server has stored specific print data and specific condition data indicating a specific print condition to a storage unit according to an instruction from a terminal device. The printer may acquire the specific print data and the specific condition data from the storage unit in a case where the predetermined notification is received. The printer may cause a print executing unit to execute printing of an image represented by the specific data according to the specific print condition indicated by the specific condition data.
