This application relates to the field of mobile communications, and in particular, to a technical solution of sharing data with a nearby device by using a wireless communications technology. In a method for printing a photo, a mobile phone first selects a to-be-printed photo, then discovers a nearby device by using the foregoing related wireless communications technology, and displays the discovered device such as a printer or a projector on the mobile phone; and then a user performs a tap operation on the discovered printer, so that one-tap printing can be implemented. In this way, printing efficiency of an electronic device is improved, and user experience is also improved.
