In a networked printing environment having at least a number of workstations of users, a management unit maintains logic storage spaces in a memory, each allocated to a respective user. Digital data files sent from a user's workstation for printing 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 and, if necessary, creates a logic storage space for the relevant user and stores the file in the logic storage space of the relevant user. The same techniques are also used for scan and copy jobs. 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.

Signal elements are mapped to a limited range of identifiers by emulating a “virtual” space of identifiers larger than the real limited space of identifiers. The larger virtual identifier space is implemented by an intermediate memory, which provides storage of identifiers assigned from the real space of identifiers. For each signal element to be mapped to an identifier, the intermediate memory is addressed by a hash value calculated from at least part of the signal element, thus allowing access to an identifier. The larger virtual space gives a better distribution of signal elements to the identifiers; and reduces the probability of different signal elements being mapped to the same identifier (“clashing”). For an efficient reduction of the clashing probability, identifiers with a low probability of being active are assigned to the intermediate memory to represent new signal elements.
