You can customize smart print with the SmartPrintRule Collection editor.

This editor is launched from the Properties window by selecting sheet in the drop-down box on the right side of the designer, selecting PrintInfo, and then clicking on the button for SmartPrintRules collection.

The left side of the editor allows you to see the list of rules. You can click Add or Remove to add more rules or remove specific rules. Navigation arrows in the middle of the editor let you move up and down the list of rules.

The right side lists the Properties window for the rule selected in the members list.

Click OK when done.
