Ghostscript is a set of essential tools for those people that have to work with PDF and PostScript files.

There are many applications that require the installation of PostScript to be able to print out PDF documents.

You will have to install it if you want to configure a virtual printer with a PDF format output.

Ghostscript has a series of services that provide:

An interpreter for PostScript language and for PDF, capable of transforming these files into various rasterized formats; visualize them on the screen and print them out with printers in which this language hasn´t been implemented.

Furthermore, Ghostscript can transform the files from PostScript language to PDF and vice versa.

If you work a lot with PDF, this is the tool you need for correctly printing your documents.
