Abstract: PROBLEM TO BE SOLVED: To perform local printing operation on a thin client by constituting the print rendering server so that a print job in printing ready form is generated and then sent back for local printing operation on the thin client. SOLUTION: A printing subsystem 125 in the printing rendering server 103 selects one of correct device drives 127 to 127 for a target printer device 105 by using a device ID. This device driver generates a printing job in PRF form by using job properties and printer device properties, then sends it to a print router 129. The printing router 129 sends the print job to a printing receiver 113 on the thin client 101 by using routing information in the print job. The printing receiver 113 after receiving this printing job sends it to the local printer device 105.

Abstract: A print rendering server system in a network computing environment perform many of the most compute intensive tasks in the overall print process for a plurality of resource limited clients. In response to a print request from the client, a print job in a print ready format is produced and sent back for local printing by the resource limited client system.

Abstract: The present invention is directed to a system and method of managing logical device state information within an information handling system. Logical device state information is stored only once, by the information handling system. Device drivers do not need to maintain and store redundant copies of logical device state information. A device driver indicates whether or not it needs to have logical device state information passed to it. Before calling a device driver to handle a device function, the information handling system checks to determine whether or not the device driver has indicated that it needs logical device state information passed to it. If so, the information handling system passes the appropriate logical device state information to the device driver. For device functions which are not hooked by the device driver, the information handling system maintains the device state. System efficiency is increased, as each device driver may register for the subset of functions it can most efficiently handle, without hooking operating system functions or handling all state specific functions associated with a particular device function. In addition, device driver development may proceed in an incremental fashion, and device driver developers do not have to learn details of every operating system on which a device may be installed.

Abstract: A print rendering server system in a networked computing environment performs many of the most computationally intensive tasks in the overall print process for a plurality of resource limited clients. In response to a print request from a client, a print job in a print ready format is produced by the print server system and is then sent back for local printing at the resource limited client system. Also disclosed is a thin client running applications making print requests using graphics API calls and further comprising a device independent format (DIF) generator for generating a DIF datastream from the graphics API calls, and a DIF sender for routing the DIF datastream and printer information via a network to a print rendering server. The advantages of the invention are that it allows a thin client to remain of limited physical resources (memory, hard disk space, processing power etc.) without the need to process printer spooling and control functions, or maintain locally a large set of resources (such as drivers) for different types of printer.

Abstract: La presente invencion se dirige a un sistema y método para administrar informacion de estado de dispositivo logico dentro de un sistema de manejo de informacion. La informacion de estado de dispositivo logico se almacena solamente una vez por el sistema para manejo de informacion. Los controladores de dispositivo no requieren mantener y almacenar copias redundantes de informacion de estado de dispositivo logico. Un controlador de dispositivo indica si requiere o no que se le transfiera la informacion de estado de dispositivo logico. Antes de requerir que un controlador de dispositivo maneje una funcion de dispositivo, el sistema de manejo de informacion verifica para determinar si el controlador de dispositivo ha indicado o no que requiere que se le pase la informacion de estado de dispositivo logico. De ser así, el sistema de manejo de informacion pasa a la informacion de estado de dispositivo logico apropiado al controlador del dispositivo. Para funciones de dispositivo que no se están enganchadas por el controlador de dispositivo, el sistema para manejo de informacion mantiene el estado de dispositivo. La eficiencia del sistema se incrementa, ya que cada controlador de dispositivo puede registrar para el subconjunto de funciones que puede manejar más eficientemente sin enganchar las funciones de sistema operativo o manejar todas las funciones específicas de estado que se asocian con una funcion de dispositivo particular. Además, puede proceder el desarrollo de controlador de dispositivo en una forma incremental, y quienes desarrollan los controladores de dispositivo no tienen que aprender los detalles de todo sistema operativo en el que puede instalarse un dispositivo.
