xfprint4 : unlogical configuration

[Rob Lahaye]

Hi,

I find it a bit annoying to have two totally different configuration
dialogs for xfprint4:

1) Xfce Settings Manager -> Printing system
   for selection of printing to 'file' or 'lpr-printer'

2) The xfprint4 dialog
   for doing all other stuff, such as file-selection, pretty-print
   etc.

For the user's convenience, I suggest to add a file/printer choice
to xfprint4 dialog.
The Printing system in Xfce Settings Manager should then have the
"default" selection (file/printer); and the xfprint4 dialog should
allow you to deviate from this default selection.

I often alternate between printing to file and to printer.
The amount of clicks and dialogs needed in xfce to get everything
set up each time is far too much!

Rob.
