A bit involved, given the process boundaries, and idles always make me a little
nervous, but I think it's a great approach overall, keep rocking like this

This is a bit weird, we would usually have a typedef PlatformPrintInfo for
these unifdef'ed cases, wouldn't we? Not a problem with the patch, though =)

I think we should add a GKeyFile especialization to GOwnPtr.

Nit: I think this would be more readable as if (printerName && !strcmp(...)),
then you can drop the braces.

This looks a bit confusing, would be more readable using the early return
pattern:
if (!selectedPrinter)
return FALSE;
… rest of the code …
return TRUE;

Could this be moved to right after the m_printJob check, so we return as early
as possible? Wouldn't impact much, but still.... =)

This looks like it's the same as pages.size(), what do you think of doing away
with it? Btw, I think we should use the m_* style for these as well.

How about turning this into a method that does return m_totalPrinted ==
pages.size()?

See bellow.

'printPages' and 'doRotate' confused me a bit, given their imperative names.
How about m_needsRotation and m_pagesToPrint (with the appropriate changes to
the accessors)?
