Abstract: A method is described comprising associating (104) a first identifier with a print job, holding (106) the print job without it printing, and releasing (108) the print job to print when a device is activated to provide a second identifier and the second identifier is related to the first identifier. An apparatus is also described comprising a receiver (18) of a print job which is associated with a first identifier, and an interface to a device (22) which provides a second identifier. The receiver (18) is configured to initially hold the print job without it printing, and the receiver (18) is configured to cause the print job to be printed by a printer (20) when the device (22) is connected to the interface, the second identifier is obtained from the device (22) and the second identifier is related to the first identifier.
