<p>A digital image reproduction apparatus is described, comprising a printer unit, a memory, an operator control unit, integrated in the apparatus, provided with a keyboard and a display, for a user to give operating commands to the apparatus, a network connection unit for coupling to a network for the purpose of communication with a digital external environment which comprises at least a number of workstations of users, a management unit connected to the said printer unit, memory and network connecting unit and, via the network connection unit, to the said workstations, which management unit maintains logic storage spaces in the memory, each allocated to a respective user. Digital data files sent from a user's workstation for printing by the printer unit contain an identification of the relevant user and are either of a first type or of a second type. The first type is formed by files which must be printed automatically, and the second type is formed by files which must be stored in the logic storage space of the user in the memory and may be printed only on a command from the operator control unit, which command identifies the relevant file. When handling a print job, the management unit checks, whether the job can be performed completely. If this appears not to be the case, the management unit converts the file into a file of the second type, if necessary creates a logic storage space for the relevant user and stores the file in the logic storage space of the relevant user. Reasons why it may not be possible to perform a job completely, are, for instance: the sender of the print job is not authorized to have jobs printed on the particular device there is no print paper available of the kind specified in the job the job is broken off by a stop command by an operator a non-recoverable machine error takes place. The same mechanism is also used for scan and copy jobs in the latter two cases mentioned above. As a result, the file is not lost but remains available. On a command from the apparatus operator control panel, it can be retrieved and the job resumed. <IMAGE></p> |
