Patent ID: 8064081

Claim:
A print system comprising a host device and a printer for transmitting print data from the host device to the printer by radio communication to perform printing, wherein the host device comprises: a first connection unit configured to connect to the printer based on a predetermined profile, wherein the profile includes designations of a control channel and a data channel; an acquisition unit configured to acquire registration information indicating whether or not the host device has been registered in the printer from the printer connected by the first connection unit using the control channel designated by the predetermined profile; a determination unit configured to determine whether or not two-way communication is possible for the host device using the data channel designated by the predetermined profile; and a first notification unit configured to notify the printer of information indicating that the two-way communication is possible in accordance with the registration information acquired by the acquisition unit in a case where it is determined by the determination unit that the two-way communication is possible, and to receive status information of the printer from the printer using the data channel, wherein the information indicating that the two-way communication is possible is not notified to the printer in a case where it is determined by the determination unit that the two-way communication via the data channel is impossible, and wherein the printer comprises: a second connection unit configured to connect to the host device based on the predetermined profile; a registration unit configured to register identification information of the host device in a registration area and transmit the registration information indicating that the host device has been registered in the printer to the host device using the control channel in response to a request by the acquisition unit; and a second notification unit configured to notify the host device of the status information of the printer using the data channel in a case where the information indicating that the two-way communication is possible is notified by the first notification unit, wherein the registration unit transmits device ID information to the host device identified by the identification information registered by the registration unit, wherein the device ID information identifies the printer and includes the registration information indicating that the identification information has been registered, and wherein the device ID information includes information indicating that a maximum number of identification information of host devices has been registered in the printer.
