The 1.9 series versions have a new config system.
See http://wiki.geda-project.org/geda:gaf_utility and gaf(1) for
details.

In your case you can just do:
  gaf config --user gschem.printing monochrome true

You can export pdf using either gschem print dialog or 'gaf export'
command. These are different ways and they use different settings. In
the first case, the 'gschem.printing' settings will be used; and you can
find the required settings for the second case if you'll read the above
pages.

gschem has different color maps for viewing and printing. See
  http://wiki.geda-project.org/geda:gschem_ug:config
You can also make your own printing color map which will suit your
needs. If you want, you can use this way to make B&W colormap and even
make some elements (e.g. square end cues of unconnected nets) invisible
when printing.
