Highlight the columns and rows that you wish to print. Click FILE, and click on PRINT AREA, then click SET PRINT AREA. If you have multiple areas that you wish to print, but they are split by a column or a row (s), then highlight the column/row(s) that you need, and hold CTRL key to move to the next selection needed, then proceed to set print area.
FYI: Check your Print Preview to make certain that you have the columns you need first before you click print.
