Plotting

Two part question please. Am a long term auto cad user switching to DraftSight.  First scaling in the (layout) sheet set. Previously could open the viewport and type "scale" "1/48XP" and the viewport would set to 1/4" scale so it could be plotted accurately. The procedure is different in this program apparently, but have been unable to discern what the procedure is? Secondly, how to install a plotter or printer to be recognized by the program so the drawing can be printed ?  Thank you.
