Print a custom area of the map?

How can i print custom area of the map? 

There’s a little “workaround” if you would like to print a map:

1. Open a flight that is NOT within the area you would like to print.

2. Change the view so you see exactly what would you like to print. 

3. File > Page Setup > General. Tick Route, untick all other options in Print What.

4. Change to Route tab in the top of this dialog.

5. Print what > Selection.

6. Select Custom scale (like 1:500000 if you like).

7. Change Page overlapping if you would like to print on several pages and then glue them together.

Use Print/Print Preview buttons to see what you have done.
