The Cheque I had printed is damaged. Can I create/re-print a Cheque with the same Cheque number?

If you want to use same cheque then Go to Reports > Cheque Book Detail.
Select the ledger which Cheque number you want to reuse.
Select the Cheque Book of that ledger. Then click on "Show" button
Then click on that cheuqe number.
The "Mark Available" button will enable, click on that button and you can reuse that cheque.
