HP Color LaserJet Managed MFP E57540 Driver Download – In computers, a printer driver or a print processor is a fragment of software on a computer that converts the data to be printed to a format that a printer can understand. The strive for of printer drivers is to allow applications to pull off printing without mammal au fait of the obscure details of each LaserJet E50000 printer model.
Printer drivers should not be confused later print spoolers, which queue print jobs and send them successively to a printer.
In complement to mammal install-able on a computer, drivers could after that be present in the embedded firmware of printers and made easy to use through a networking protocol e.g. IPP. The embedded firmware of a printer could fittingly eliminate the need to install any driver on a computer, by cooperative print data in a general-purpose format e.g. PDF via a networking protocol. Despite some efforts to standardize various stages of the printing pipeline, printer interfaces are largely nevertheless no question proprietary and manufacturer-specific. Hence, plants of functions performed by LaserJet E50000 drivers can vary. Nonetheless, based on the action performed, drivers can be classified as follows.
LaserJet E50000 Device-independent converters
These drivers can convert print data from one general strive for format e.g. PDF, DVI etc to other general-purpose format e.g. PS. Examples count up Ghostscript, etc.
Converters to device-specific format
These drivers convert print data from one format e.g. PS to a unmodified device-specific format that the printer hardware can process and create a print. These LaserJet E50000 drivers battle as the last stage in delivering a print job to the printer. These drivers are more likely to be embedded in printer firmware.
LaserJet E50000 Packaging formats
Install-able drivers can be packaged in various formats. PPD is a popular packaging format for drivers that take p.s. data or PDF data as input. Due to dominance of choose working systems, the working systemdriver interface is more standardized than LaserJet E50000 driver printer interfaces. fittingly there is more standardization in packaging formats of drivers than the actual functions performed by drivers.
-PostScript Printer tab file Usually the working system needs to know the characteristics of a printer. The PPD files are the normal mannerism to supply this information. They LaserJet E50000 have the advantage of mammal system independent, and there is a freely easy to use large database of them, Foomatic.
-CUPS filter This format is used by CUPS on Linux systems.
