I don't know of any gtkmm examples for this, but the basic concepts
are fairly simple:

in your 'draw page' handler, (e.g. on_draw_page()), get the cairo
context from the Print context (e.g. context->get_cairo_context()).
Then draw the image into the cairo context.  You can use any of the
cairo drawing operators (move_to(), line_to(), fill(), etc), or if you
want to print an image from file, you can create a Cairo::ImageSurface
from a png (Cairo::ImageSurface::create_from_png()) and paint this
into the cairo context.  If you want to print a Gdk::Pixbuf, you can
look at the function "eog_window_print_draw_page()" for inspiration.
it should translate to gtkmm/cairomm fairly easily:

Hope that helps
