printer macro

[alpine4133]

I need to print a area but hide some column each time I print. I get an error message with this. Can someone help me fix this macro?

I want to Hide column K &L, and then unhide after I print.

Sub print_route()
    .Columns("K:L").EntireColumn.Hidden = True
  ActiveWindow.SelectedSheets.PrintOut Copies:=1, Collate:=True
    .Columns("K:L").EntireColumn.Hidden = False
End Sub
