Lazy Initialize QPrinter

Browse source 
it was taking 3 - 4 secs here to open the print dialog,
first I tought it was a bug in our side, but it looks like
it's a Qt bug, and by lazy initializing it we don't actually
solve this, since it will still take 3 - 4 secs for the printer
to start, but the dialog will appear much quicker.
