Abstract: A computer network comprises first, second, and third computer systems connected to first, second, third and fourth print devices by means of a network connection. Each computer system comprises at least one application program capable of generating print data for output to one or more of the print devices. A server is also connected to the network connection, the server comprising a workflow management program which monitors and controls the flow of print jobs which are sent by the first, second, third and computer systems. The workflow management program maintains a computer model representing the up-to-date state of the system. In response to a new event occurring in the system, such as a hardware failure or a new print job, the program makes a plurality of copies of the computer model and assigns to each copy an alternative event management operation. The program generates a set of prediction data from each copy of the computer model, each set of prediction data representing the predicted future state of the system resulting from applying each respective event management operation. Next, a preferred event management operation is selected based on comparing each set of prediction data with a reference set of prediction data.

Abstract: A computer network 1 comprises first, second, and third computer systems 3, 5, 7 connected to first, second, and third print devices 9, 11, 13 by means of a network 15. Each computer system 3, 5, 7 comprises at least one application program capable of generating print data for output to one or more of the print devices 9, 11, 13. The print data is output from each application program and stored on a on a print spooler (not shown) forming part of each computer system 3, 5, 7. Each print device 9, 11, 13 comprises a daemon 23 and a local memory 19, the data control module being configured to monitor, via the network 15, print data relating to a print job stored on a computer system, the print data including job timing information relating to the preferred time at which the print job is to be processed. The daemon 23 is also configured to retrieve a copy of the print data as soon as the data link becomes available to transfer the print data, and to store the print data on the local memory 19, the retrieval and storage operations being performed prior to the time specified in the job timing information. Accordingly, each print device 9, 11, 13 maintains a local storage of print data, the print data being retrieved and stored prior to the time specified in the job timing information at a time when the data link between the print device and a computer to which it is connected is capable of allowing the transfer, i.e. when the network traffic is low.

Abstract: An information technology network comprises a plurality of printers and at least one computing entity which serves as a print manager. The print manager is adapted to process print jobs by distributing the ripping process between two or more different printers, and then returning disparately ripped data to a single printer for physical marking of documents with indicia in accordance with the ripped data.

Abstract: A method and associated control apparatus are used to control the operation of a plurality of independent printing devices each having at least one holder. The control apparatus is arranged to store information relating to one or more print jobs scheduled to be performed by each of said plurality of printing devices. This information includes the quantity of media required to complete each of the print jobs. The control apparatus learns an initial or current quantity of media held in one or more of said printing devices and estimates or otherwise determines the quantity of media remaining in a media holder of a printing device during the performance of a print job. The control apparatus generates an alert when said quantity of media reaches a predetermined minimum value indicating that more media will be required to accommodate a particular print job.

Abstract: Print jobs requested are scheduled to be performed during available time slots, and on suitable printers having lowest associated overhead cost. In the event that no technically suitable printer is available a print services management programme determines whether it is economically viable to cancel one or more pre-scheduled print jobs in favour of the requested job, taking into account, for example, the price of the requested job and scheduled jobs. In a development a bidding routine establishes at what price it is viable to cancel a scheduled job in favour of a requested job, and that price is then offered to a customer. Future work inflow is predicted and represented in the form of virtual jobs which are scheduled in the same manner as actual jobs, but whose value is representative of the likelihood of the job maturing into an actual job. In a further development, demand on printer hardware arising from the scheduling of virtual jobs is used to monitor predicted future hardware requirements, and when virtual demand exceeds a threshold, an order is placed for procurement of further hardware.

Abstract: The entirety of a web page, including clickthroughs, is cached at a location within a network intermediate a client requesting the page and the host web site for the page. Activation of a clickthrough, whether held in session cache on the client machine, or in the network cache causes a javascript program to generate an activation identifier giving the IP address of the machine activating the clickthrough and the time. This ID, together with an ID giving the IP address from which the web page originally hosting the clickthrough was retrieved is sent to the host web site, enabling them to prove their role in the establishment of communication between the client and the site targeted by the clickthrough. The generation of such identifiers also has applicability in the field of text messages, e.g. sent out by a publicity agent, and actuable to connect to a telephone number held by an enterprise within the telephone network. Activation of such a text message results in the return of suitable identifiers to the publicity agent to enable them to seek remuneration from the enterprise.

Abstract: An information technology network comprises a plurality of printers and at least one computing entity which serves as a print manager. Print jobs are distributed speculatively to a plurality of printers, which determine locally whether to proceed with the allocated job. Duplication of a job, by two or more printers is prevented by an appropriate communication protocol between printers.

Abstract: An information technology network includes a plurality of printers, at least two of which run a distributed print management programme. The programme operates to monitor all network traffic by snooping, and on the basis of monitored network traffic maintains a log of network printers, their capabilities and status. In addition the programme repeatedly checks for print job notices placed on a spooler, determines on the basis of the updated log which printer under its management is most appropriate to perform the outstanding job, and that printer to retrieve the outstanding job notice and perform the job. Conflicts between different printers retrieving the same job are either resolved by leader election, or preventing conflict by invoking the use within the spooler of a processor instruction known as TEST/SET.
