Abstract
In response to a request from a host device using an initial protocol, capability information including information indicative of a plurality of communication protocols is returned to the host device, and a communication protocol, designated by the host device based on the capability information, is set, and print data is received from the host device by the set communication protocol. In a system using an interface connected to various types of devices, e.g., an IEEE 1394 serial bus, a communication protocol, which is used when a host device transfers print data to a printer, is not limited to that unique to the manufacturer of the device.
