The XPS format used in the spool file represents advanced graphics effects such as 3D images, glow effects, and gradients as Windows Presentation Foundation primitives, which printer drivers could offload their rasterization to the printer in order to reduce computational load if the printer is capable of rasterizing those primitives.
Microsoft claims that major printer vendors are planning to release printers with built-in XPS support and that this will provide better fidelity to the original document. [23] At the core of the XPS print path is XPSDrv, the XPS-based printer driver which includes the filter pipeline.
In computers, a printer driver or a print processor is a piece of software on a computer that converts the data to be printed to a format that a printer can understand. The purpose of printer drivers is to allow applications to do printing without being aware of the technical details of each printer model.
These functions include smart card readers, direct connection to digital cameras (e.g. PictBridge technology) and other similar uses. The print engine of most All-in-one devices is based either on a home desktop inkjet printer, or on a home desktop laser printer. They may be black-and-white or colour capable.
Some "generic" GDI drivers such as pnm2ppa have been written; they aim to make GDI printers compatible with non-Windows operating systems such as FreeBSD, but they cannot support all printers. [ 11 ] In order to allow simpler creation of drivers for Winprinters, the Microsoft Universal Printer Driver was created.
Printer Command Language, more commonly referred to as PCL, is a page description language (PDL) developed by Hewlett-Packard as a printer protocol and has become a de facto industry standard. Originally developed for early inkjet printers in 1984, PCL has been released in varying levels for thermal , matrix , and page printers.
