Abstract: In a method and system for storage and retrieval of print data, print data of a print job are transferred in blocks from a data source to at least two of a plurality of print servers connected with one another via a network. Control data regarding respective print data are transmitted to the print servers and are registered and stored in the network. Control data are registered by a central control module of the network and further processing of the print job is allocated by the central control module to an allocated print server so that the allocated print server receives the control data. Using the control data, the respectively allocated print server reads the print data in blocks from the respectively associated print server, processes and/or buffers them as needed, and forwards them to a processing device.

The fixing unit has at least one wall designed to hinder a heat transfer from the fixing unit to the transport unit.

Abstract: A method and a device for accessing data wherein the data is sequentially stored as data objects. The data objects are identified by a control variable having consecutive integer values. The control variable and the memory address is determined of a first known data object and an estimate for the size of a data object is determined therefrom. The control variable of the requested data object is multiplied by the estimate, as a result whereof an initial value for a memory address of the requested data object is formed. The actual control variable of the data object stored under the initial value is determined, the search for the requested data object being terminated in the case of correspondence between the actual control variable and the desired control variable, and otherwise the search is continued.
