The documentation about PPD extensions

http://cups.org/documentation.php/doc-1.4/spec-ppd.html

introduces the keyword

*cupsBackSide:

under "General Attributes". The keyword is explained and in the description is told that "cupsFlipDuplex" is deprecated by this keyword. In the source code of CUPS 1.3 (cups/ppd.c) only the deprecated "cupsFlipDuplex" and not the new "cupsBackSide".

Also in the CUPS Raster output device (cups/gdevcups.c) the new "cupsBackSide" is not supported.

The flip_duplex member of ppd_file_t only tracks cupsFlipDuplex and changing that would break the ABI.

While you could argue that we should set it for "*cupsBackSide: Flipped", any RIP implementation will need to look at the new PPD keyword anyways so this is "not to be fixed".
