摘要： Print jobs are automatically and transparently spooled in a device-independent format, such as an enhanced metafile format. The enhanced metafile format provides a format into which documents are readily converted and which occupies a minimal amount of storage space. Each spooled print job is asynchronously printed relative to a program that requested the print job. Such spooled print jobs are de-spooled in a background processor mode. An operating system provides the resources for converting a print job into enhanced metafile format and spooling the print job in the enhanced metafile format.

摘要： Facilities are provided within an operating system for supporting deferred printing of print jobs. The process of spooling a print job and the process of despooling the print job are decoupled, such that a printer need not be available at the time of spooling. Print jobs are spooled in a device-independent format, such as the enhanced metafile format. The print jobs may be spooled without a printer driver being installed for a target printer or without the target printer being connected to the system. Later, when the target printer becomes available, the print job is despooled and printed. A configuration database holds different printer configurations that list available printers in different environments. For example, a user may have a different configuration for printers available when he uses his computer at home, at work and on the road, respectively. The configurations help the user to identify the printers that are currently available and those that are available in other settings. When a currently active machine configuration changes, the system checks for spooled jobs on printers that were previously unavailable and are now available and asks the user if the user wishes to start printing these spooled print jobs.

摘要翻译：在操作系统中提供设备，以支持打印作业的延期打印。打印作业的后台处理和打印作业的分离过程被解耦，使得打印机在假脱机时不需要可用。打印作业以与设备无关的格式假脱机，例如增强的图元文件格式。无需为目标打印机安装打印机驱动程序，或者目标打印机未连接到系统，打印作业可能会被假脱机。之后，当目标打印机变得可用时，打印作业被去除和打印。配置数据库保存不同的打印机配置，列出不同环境中的可用打印机。例如，当用户在家中，在工作中和在道路上分别使用他的计算机时，用户可能具有不同的可用打印机配置。配置帮助用户识别当前可用的打印机以及其他设置中可用的打印机。当当前活动的机器配置更改时，系统将检查以前不可用并且现在可用的打印机上的假脱机作业，并询问用户是否希望开始打印这些假脱机打印作业。

摘要： An operating system provides a point-and-print capability to users of the workstation. The point-and-print capability allows a user to print on any printer available within a distributed system by simply selecting a printer and requesting to print on the printer. The retrieval of configuration information and installation of the printer is performed transparently relative to the user of the workstation. The required printer configuration information is retrieved from a database that is maintained at a network server for the network that includes the target printer. A heuristic technique is employed to obtain complete printer configuration information when such printer configuration is not fully available from the network server.

摘要： A computer method and system for configuring device driver is provided. In a preferred embodiment, a device driver comprises a minidriver associated with each output device and a universal driver. Each minidriver implements a plurality of minidriver functions for controlling the outputting of data to the output device by invoking functions of the universal driver. During execution of a program, the program selects an output device and invokes the minidriver functions of the minidriver associated with the selected output device. An initialization function of each minidriver invokes an initialization function of the universal driver passing an indication of and attributes of the selected output device. Other minidriver functions invoke an analogous function of the universal driver passing an indication of the selected output device. The initialization function of the universal driver processes the passed attributes and stores the indication and the processed attributes. Each analogous function accesses the stored attributes and performs the behavior of the analogous function to effect the controlling of the output device.
