This advanced print driver has the ability to discover HP print devices and automatically expose the client to device capabilities (e.g., duplex, color, finishing, etc.). HP Universal Print Driver is a Microsoft Windows-only solution with two modes: Traditional Mode and Dynamic Mode. In Traditional Mode, HP UPD behaves similarly to traditional ...
In many cases programs may appear to be hung, but are making slow progress, and waiting a few minutes will allow the task to complete. Modern operating systems provide a mechanism for terminating hung processes, for instance, with the Unix kill command, or through a graphical means such as the Task Manager's "end task" button in Windows (select the particular process in the list and press "end ...
A Deferred Procedure Call (DPC) is a Microsoft Windows operating system mechanism which allows high-priority tasks (e.g. an interrupt handler) to defer required but lower-priority tasks for later execution. This permits device drivers and other low-level event consumers to perform the high-priority part of their processing quickly, and schedule ...
Nowadays, the most common use of spooling is printing: documents formatted for printing are stored in a queue at the speed of the computer, then retrieved and printed at the speed of the printer. Multiple processes can write documents to the spool without waiting, and can then perform other tasks, while the "spooler" process operates the printer.
Tiled printing is a method that computer programs use to enable users to print images larger than a standard page. This method was popularized by a program called The Rasterbator . A tiled printing program overlays a grid on the printed image in which each cell (or tile) is the size of a printed page, and then prints each tile.
A virtual printer is a piece of computer software whose user interface and API resembles that of a printer driver, but which is not connected with a physical computer printer. A virtual printer can be used to create a file which is an image of the data which would be printed, for archival purposes or as input to another program, for example to ...
The message loop is an obligatory section of code in every program that uses a graphical user interface under Microsoft Windows. [1] Windows programs that have a GUI are event-driven. Windows maintains an individual message queue for each thread that has created a window. Usually only the first thread creates windows.
The scheduler is an operating system module that selects the next jobs to be admitted into the system and the next process to run. Operating systems may feature up to three distinct scheduler types: a long-term scheduler (also known as an admission scheduler or high-level scheduler), a mid-term or medium-term scheduler, and a short-term scheduler.
