Contributed by German foundry URW++ in 1996 under the GPL and AFPL, this collection includes 35 font styles from 10 typeface families and is therefore commonly called the URW Base 35 fonts or URW Core 35 fonts.There are several sets of free fonts supplied for Ghostscript, intended to be metrically compatible with common fonts attached with the PostScript standard.

Virtual printers can also create PDF files.

Such GUIs include Evince, IrfanView, Inkscape and PDF24 Creator. Ghostscript graphical user interfaces (GUIs) view PostScript or PDF files on screens, scroll, page forward, page backward, zoom text, and print pages. Scripting the new C written PDF interpreter from PostScript is still possible. The new default PDF interpreter has been rewritten in C entirely, and is faster and more secure than its predecessor, while its interface and graphics library have not changed. Until spring 2022, up to Ghostscript version 9.56.1, the default PDF interpreters implementation itself was coded in PostScript. Starting with release 9.55.0 Ghostscript has two build-in PDF interpreters. which raised license compatibility questions, for example by Debian. In February 2013, with version 9.07, Ghostscript changed its license from GPLv3 to GNU AGPL. According to Artifex, as of version 9.03, the commercial version of Ghostscript can no longer be freely distributed for commercial purposes without purchasing a license, though the (A)GPL variant allows commercial distribution provided all code using it is released under the (A)GPL.

Ghostscript is currently owned by Artifex Software and maintained by Artifex Software employees and the worldwide user community. With version 8.54 in 2006, both development branches were merged again, and dual-licensed releases were still provided. Later, Deutsch formed Aladdin Enterprises to dual-license Ghostscript also under a proprietary license with an own development fork: Aladdin Ghostscript under the Aladdin Free Public License (which, despite the name, is not a free software license, as it forbids commercial distribution) and GNU Ghostscript distributed with the GNU General Public License. Peter Deutsch for the GNU Project, and released under the GNU General Public License in 1986. Ghostscript has been ported to many operating systems, including Unix-like systems, classic Mac OS, OpenVMS, Microsoft Windows, Plan 9, MS-DOS, FreeDOS, OS/2, ArcaOS, Atari TOS, RISC OS and AmigaOS.

As it takes the form of a language interpreter, Ghostscript can also be used as a general purpose programming environment.

Ghostscript can also serve as the back-end for PDF to raster image (png, tiff, jpeg, etc.) converter this is often combined with a PostScript printer driver in ' virtual printer' PDF creators. The ps2pdf conversion program comes with the Ghostscript distribution. It can also be used as a file format converter, such as PostScript to PDF converter. Ghostscript can be used as a raster image processor (RIP) for raster computer printers-for instance, as an input filter of line printer daemon-or as the RIP engine behind PostScript and PDF viewers.
