pdftopdf - A filter that converts PDF files to another format, such as PostScript or PCL.
pstops - A filter that rearranges pages in a PostScript document for duplex printing.
foomatic-rip - A filter that converts printer-specific data into a format that CUPS can understand.
imagetoraster - A filter that converts image files to raster formats suitable for printing.
dnssd - A backend that allows printers to be discovered using DNS Service Discovery (DNS-SD).
Cupsfilters is designed to work with CUPS on Unix-like operating systems, including Linux, macOS, and BSD. It is released under the GNU General Public License (GPL) version 2 or later.
