Depends on the situation.
Also, I personally would love to see wxWindows support direct
PS generation on non-Unix platforms so that you'd get better quality
output on Windows (etc.) AND could also easily move to direct PDF
output for all platforms.

To what type of printer? Are you using something like the
GimpPrint extentions or just direct through GS? What version of GS?

Depends on the version of GS. They are in the midst of
switching over all the graphics subsystems for the 8.0 series -
including moving to FreeType for the font renderer.

Pango just gets the outline data from FT - it doesn't read
the hint tables, etc.

Nope, not necessary...

I believe that Dom was working on (completed?) support for
this in AbiWord ...
