Print: display an error message if no printers are found

Browse source 
When pressing Print or Preview from the PrintDialog, we need
to first check if there are printers installed. If not
we abort and show an error message.

This is needed because if no printers are installed,
things like the reported page height could be zero and
the profile and table print code in PrintLayout will
break.
