User is trying to print checks using the check style Voucher, but does not want the Notes section to show up at the bottom.
The Notes section on the check contains the memo that you added to it. If you do not want it to show up on your printed checks, you can try using any of the other check styles in the Print Checks screen. Check the Core Help for details. If none of the styles meet your requirements, you can have our Customization Team create a custom one.
