Not exactly, because when rendering to a pixbuf cairo backend is used too.

I've just found the problem. It's a bug in the glib frontend. The problem is that image prescaling is disabled when rendering for printing, and printing is initialized to True in CairoOutputDev. We are calling CairoOutputDev::setPrinting() in poppler_page_render but it's missing in poppler_page_render_to_pixbuf(). Now, that glib frontend depends on cairo, I'm going to change render_to_pixbuf to call poppler_page_render directly and the problem will be fixed.

Please, note that poppler_page_render_to_pixbuf() and the other GDK functions are going to be deprecated in a near future, since we are just rendering to a cairo surface and then converting to a gdk pixbuf.

Thanks for reporting.
