I started converting the check printing code to GtkPrint last weekend.

This is where I see problems.  Gnucash embeds goffice pie charts and bar
charts into gtkhtml reports.  Not a problem today as both use
GnomePrint.  I'm not sure how we could do this if gtkhtml used GtkPrint
and goffice used GnomePrint.

I'm afraid I agree.  Until goffice also converts to GtkPrint, I don't
know that we have any other course of action.
