[cups] pdftops causes duplex page premature ejection on Brother

[Richard Chan]

Thanks for the pointer; Fedora 20 has a new build 9.10-6-fc20
that fixes duplex with gs a renderer.


F20 is using CUPS 1.7.0 - the /PageSize feature is now inserted by
the pstops filter. Does this "fix" the second issue you refer to?

%%BeginFeature: *PageRegion A4
<< /PageSize [595 824] /ImagingBBox null>> setpagedevice
%%EndFeature
