Main feature would be using of GtkPrintOperation, which will handle
running GtkPrintDialog and sending jobs to server. In present evince
code the GtkPrintDialog is executed directly and pages are prepared in
evince (including "Pages per Sheet", copies, Even/Odd sheets) and send
thorough GtkPrintJob. But there are problems with the prepare. It
doesn't correctly prepare pages when you need to print duplex or
non-standard ordering of pages per sheet. There is also problem with
Even/Odd pages in "Pages per Sheet" mode with more than 1 page.
This can be handled by the Gtk+ print infrastructure itself and you
don't need to have it implemented in evince.
