| The cups-filters project at OpenPrinting (included in all Linux distributions using CUPS 1.6.x or newer) provides the filters needed to convert the print job output of desktop applications (usually PDF) into the printer's native language or into the universal CUPS/PWG-Raster format as input for a separate printer driver. It also provides the pdftopdf filter to apply page management (N pages per sheet, selected pages, even/odd pages for manual duplex, mirror for iron-on sheets, ...) to the PDF data stream. | The cups-filters project at OpenPrinting (included in all Linux distributions using CUPS 1.6.x or newer) provides the filters needed to convert the print job output of desktop applications (usually PDF) into the printer's native language or into the universal CUPS/PWG-Raster format as input for a separate printer driver.

| CUPS has two mechanisms for on-the-fly-PPD generation to avoid the wasting of disk space by thousands of uncompressed (or slightly compressed) PPD files. One is to put an executable file into the /usr/lib/cups/driver/ directory which lists and generates PPD files on request, the other is using *.drv files in /usr/share/cups/drv, which contain the data for the PPDs in a simpler and more compact format. | CUPS has two mechanisms for on-the-fly-PPD generation to avoid the wasting of disk space by thousands of uncompressed (or slightly compressed) PPD files.

| Adrian Johnson did a lot of the work needed to make cairo color managed. Finishing this work and getting the code upstream would allow us to simplify a lot of applications that use cairo. See [[http://cgit.freedesktop.org/%7Eajohnson/cairo/log/?h=color-space|http://cgit.freedesktop.org/~ajohnson/cairo/log/?h=color-space]] for the branch. Adrian has also patched Inkscape to use the new features, and that needs cleaning up and pushing upstream [[http://cgit.freedesktop.org/%7Eajohnson/inkscape/log/?h=color-space|http://cgit.freedesktop.org/~ajohnson/inkscape/log/?h=color-space]] Also see [[http://lists.cairographics.org/archives/cairo/2012-July/023353.html|http://lists.cairographics.org/archives/cairo/2012-July/023353.html]] and [[https://mail.gnome.org/archives/gimp-developer-list/2012-August/msg00084.html|https://mail.gnome.org/archives/gimp-developer-list/2012-August/msg00084.html]] for more details. | Adrian Johnson did a lot of the work needed to make cairo color managed.

| MuPDF is a lightweight PDF renderer made by Artifex, the company behind Ghostscript. In contrary to Ghostscript, MuPDF is a pure PDF renderer. It does not contain a PostScript interpreter nor parts of it are written in PostScript. This makes it smaller, faster, and less resource-consuming, the ideal solution for mobile devices like tablets or smartphones. | MuPDF is a lightweight PDF renderer made by Artifex, the company behind Ghostscript.
