GNU Ghostscript ----------------- This is Debian's prepackaged version of GNU Ghostscript. It was packaged by Torsten Landschoff from sources obtained from the Ghostscript sourceforge project. Obviously GNU Ghostscript itself is licensed unter the GPL (below). There is some additional stuff included in this package as well: - PCL3: A driver for printers supporting the PCL3 standard written by Martin Lottermoser. The homepage is at http://home.t-online.de/home/Martin.Lottermoser/pcl3.html This is licensed under the terms of the LGPL which you can find in /usr/share/common-licenses/LGPL on Debian systems. This package is based on the driver contained in http://home.t-online.de/home/Martin.Lottermoser/pcl3dist/pcl3-3.3.tar.gz - Samsung SmartGDI driver: According to www.linuxprinting.org this driver was released by Samsumg themselves but got lost during a website reshuffle. It is available via http://www.linuxprinting.org/download/printing/samsung-gdi-driver.tar.gz and licensed under the GPL. - Gimp Print Ghostscript driver: That driver was downloaded using the Debian source package gimp-print. You should be able to find the upstream via www.gimp-print.sourceforge.net as well. As you might expect this is also licensed under the GPL.
