Abstract: The application relates to a method for operating a printing system with a printing server and a printing device that can be connected to the printing server. The printing system is configured to obtain a print job encrypted with a public print job key from a computer connected to the printing server and to receive a private print job key encrypted with a public printing device key from a mobile user terminal. The received encrypted print job is subsequently sent to the printing device for printing.
