according to claim 4, wherein the communication apparatus displays the list based on information included in the first NAN Attribute and/or the second NAN Attribute transmitted by the one or more printers discovered by the communication apparatus. ### Claim 6 (depends on 5) The communication apparatus according to claim 5, wherein the communication apparatus displays information included in the Service Info included in the first NAN Attribute. ### Claim 7 (depends on 4) The communication apparatus according to claim 4, wherein the communication apparatus searches for the one or more printers for the print service and one or more other apparatuses for another service by the first communication, and the communication apparatus displays a list of the discovered one or more printers and the discovered one or more other apparatuses by dividing the discovered printers and the discovered apparatuses in accordance with the service. ### Claim 8 (depends on 1) The communication apparatus according to claim 1, wherein the execution of the instructions further causes the communication apparatus to: store, in a case where the communication apparatus executes communication by the second communication, connection setting information used in the communication, wherein the communication apparatus performs control so as to establish the connection in the wireless LAN by the second communication by using the connection setting information stored in the communication apparatus, before executing the search for the one or more printers by the first communication. ### Claim 9 (depends on 1) The communication apparatus according to claim 1, wherein the execution of the instructions further causes the communication apparatus to: accept an operation by a user, wherein the communication apparatus starts the search for one or more printers by the first communication in response to accepting a predetermined operation related to the print service. ### Claim 10 (depends on 9) The communication apparatus according to claim 9, wherein the predetermined operation comprises one of an operation to indicate the start of the print service, an operation to activate a predetermined application, an operation to start a search for a printer which provides the print service, an operation to power on the communication apparatus, and an operation to cause the communication apparatus to return from a sleep state. ### Claim 11 (depends on 1) The communication apparatus according to claim 1, wherein the communication apparatus searches for the one or more printers while a setting to enable the first communication has been made and does not search for one or more printers while the setting to enable the first communication has not been made. ### Claim 12 (depends on 1) The communication apparatus according to claim 1, wherein the communication apparatus does not execute communication using the second communication when a printer is not discovered by the first communication. ### Claim 13 (depends on 1) The communication apparatus according to claim 1, wherein the first communication is communication in which lower power is consumed than in the second communication. ### Claim 14 (depends on 1) The communication apparatus according to claim 1, wherein the first communication and the second communication are both compliant with the IEEE802.11 standard series. ### Claim 15 (depends on 1) The communication apparatus according to claim 1, wherein the communication apparatus executes the second communication by one of the communication
