Two options:
1. View > Toolbars and check Standard
the Standard toolbar has a Print button it
2. put you own button in the worksheet with VBA:
Sub button_maker()
Application.CommandBars("Forms").Visible = True
ActiveSheet.Buttons.Add(290.25, 69, 51.75, 41.25).Select
Selection.OnAction = "printit"
Application.CommandBars("Forms").Visible = False
End Sub
Sub printit()
ActiveWindow.SelectedSheets.PrintOut Copies:=1, Collate:=True
End Sub
The first sub creates a button. The second sub does the printing. This
assumes that the print range has already been established.
