The GnuCash report print bug is listed at 
http://bugzilla.gnome.org/show_bug.cgi?id=350408

After looking further into the problem, it appears that GnomePrint doesn't 
have a setable default font.  And because the pango attrs don't set a font 
face or size if the required font is the default, the result is the items are 
printed in GnomePrint default of "Serf Regular 12".  My patch changes this to 
explicitly set the pango attrs resulting with the items printed in that font.

As for the character placement problem, it appears to be a problem only with 
the [Dejavu] Sans and [Dejavu] Serf fonts at point sizes 9 and 10 when 
printing.  This maybe a Ubuntu 6.06 problem.

Looking at gtkhtml-3.14.0/src/htmlprinter.c from the most recent source, it 
appears that the new gtk_print allows the setting of a default font.  Please 
make this user accessable even if its in a gconf file.
HTMLPainter *
html_printer_new (GtkWidget *widget, GtkPrintContext *context)
{
        const PangoFontDescription *desc;
        HTMLPrinter *printer;
        HTMLPainter *painter;

        printer = g_object_new (HTML_TYPE_PRINTER, NULL);
        printer->context = g_object_ref (context);

        painter = HTML_PAINTER (printer);
        html_painter_set_widget (painter, widget);
        desc = pango_font_description_from_string ("sans 8");/* FIXME font 
hardcoded*/
        painter->pango_context = gtk_print_context_create_pango_context 
(context);
        pango_context_set_font_description (painter->pango_context, desc);
        return painter;

}
