Return error instead of showing an error dialog when printing

Browse Source 
Remove message dialogs showing an error when printing. Return
GTK_PRINT_OPERATION_RESULT_ERROR and set error in such a case.
Also return GTK_PRINT_OPERATION_RESULT_CANCEL when cancelled.
Do it for synchronous and asynchronous cases (#549127).
