Abstract
In a printing method, content of a print job is split into a main portion and a completing portion at a user terminal (10). The main portion is encrypted using the user terminal. The encrypted main portion (32) is sent to a printing device (12). The completing portion is encrypted using a mobile device (20) operatively connected with the user terminal. The encrypted completing portion (34) is stored on the operatively connected mobile device. The mobile device is operatively disconnected from the user terminal, and is operatively connected with the printing device. After the operative connecting: (i) the encrypted main portion is decrypted using the printing device and the completing portion is decrypted using the mobile device; (ii) the decrypted main portion and the decrypted completing portion are combined to reconstruct the print job; and (iii) the reconstructed print job is executed using the printing device.
