You can drag the thick blue line up/down/left/right to change the print
area.
Or you can go to menu File/Print Area/Clear Print Area to clear it and then
File/Print Area /Set Print Area to set what you want.

When you apply a print area to a worksheet, how do you then delete the
rest
of the worksheet not in your selected area ?

In worksheets where this has been done already, a thick blue line appears
around the side. How do you then undo this format and add rows and columns
to
this spreadsheet ?
