Confirm

After you close the report window, carefully examine the printed checks.  Use the Confirm button to record the successful printing of a check or checks and remove the payment from the list of checks to be printed.

If the document(s) that you selected did not print, uncheck Select for each one that did not print.  This will not delete the check; it will simply appear back in the print checks list so you can print it again.  If none of the documents printed, simply do not click on the Confirm button.
