Abstract: A printer controller arranged to control a print engine comprising: a print job storage for storing print jobs to be printed; wherein a print job may comprise a deadline, the deadline specifying an ultimate time by which the print job is to be completed; a scheduler module for determining a print execution time for each print job in a sequence of one or more print jobs, the scheduler taking into account a setup time for a print job for setting up the print engine to print the print job given a previous print job; a planning module for determining a print order for to-be-printed print jobs in the print storage, arranged to submit a plurality of sequences of to-be-printed print jobs in the print job storage to the scheduler and in response receive from the scheduler for each sequence of to-be-printed print jobs the print execution times of the print jobs; wherein the planning module elects a sequence of to-be-printed print jobs for which each deadline in a print job in the sequence is met according to the print

Abstract: A method of controlling a printing system that is arranged to process a sequence of media sheets and is operable with a finite number of different settings includes calculating a time to finish that will be needed for processing the sequence, scheduling a sequence of sheets for printing, defining a set of possible settings for processing the scheduled sequence, calculating a time to finish for each setting in the defined set, selecting the setting with the smallest time to finish, and processing the sequence with the selected setting.

Abstract: A method, system and computer program for executing a hot migration operation are provided. A hot migration operation is executed from a first version of a service using a first data model, to a second version of the service using a second data model that is modified with respect to said first data model. A service comprises a client application, a data manager and a data repository. The migrate operation is effected on a server facility that accommodates multiple processes to be running in parallel. Second version client applications, a second version data manager operating according to the second data model, and a second version data repository arranged according to the second data model and cooperating with the second version data manager are installed. The first and the second version data managers are provided each with a migration plug-in.
