Mine for text is here:
http://efax-gtk.cvs.sourceforge.net/viewvc/*checkout*/efax-gtk/efax-gtk/src/utils/text_print_manager.h
http://efax-gtk.cvs.sourceforge.net/viewvc/*checkout*/efax-gtk/efax-gtk/src/utils/text_print_manager.cpp

The guts of it are similar to yours, although it has more twiddly bits.

I do not know anything about OLPC/sugar, so I do not completely
understand all your comments about evince, since evince is a
postscript/pdf display application, rather than a library.  The
libraries it uses are as I recall, although it is some time since I
looked, poppler, libspectre and libgs.  If evince is the main display
application for sugar, though, then it already comes equipped with
printing via gtk-print, for which purpose it uses poppler/cairo and in
recent versions libspectre/cairo (I think).
