Go to Transaction Activity as if you were going to print checks. If you do not have any checks awaiting print (the system will tell you that all checks have been printed), then select the Sample command button.

Choose Select Form and make sure that Check Form 1 is highlighted in blue. (This is the default setting for Check Form Navigator and will print the check stub first and the actual check second.) Then select OK.

Then, choose Select Printer and make sure that you select Check Form Navigator. Select OK.
