A printing method, an arrangement, a computer program, and a computer-readable storage medium are provided to increase a number of printing devices used by a mobile terminal. The mobile terminal communicates with a server via a wireless communication interface and sends via the server data to a printing device including information identifying the printing device and a key assigned to the printing device. The method includes establishing a communications link, determining printing devices, transmitting information about the usable printing devices, selecting a usable printing device, transmitting the data intended for printing or information that enable the server to retrieve the data intended for printing from a remote storage location in a data network, checking the validity of one or more of the keys transmitted from the mobile terminal transmitted, and transmitting, depending on the validity of the key(s), the data intended for printing to the selected printing device.
