You can choose whether to display buttons in print preview or in printed output. You control this in the Properties view for the DataWindow object, not the Properties view for the button.
To control the display of buttons in a DataWindow object in print preview and on printed output:
Display the DataWindow object’s Properties view with the Print Specification page on top.
Select the Display Buttons – Print check box.
The buttons are included in the printed output when the DataWindow object is printed.
Select the Display Buttons – Print Preview check box.
The buttons display on the screen when you view the DataWindow object in print preview.
