With blank checks, actual check numbers are used. How do I find which numbers were used?

When printing blank checks, the check numbers are not recorded in Microsoft® Dynamics GP.
If the starting check number is not changed from the default on the Print Blank Checks screen, the next check number on the Checkbook Maintenance screen will be incremented by the number of checks printed.
If the default starting check number is changed, the next check number on the Checkbook Maintenance screen will not change. The checks printed from the Blank Checks screen are intended to be completed manually and are recorded in the system when they are entered through the Manual Payments screen. Blank checks are not recorded as voided checks because they have not been voided; they are negotiable checks.
