2.Select (tick) the "Auto-post documents on print" option.

3.Click on the OK button to save your changes. Documents will automatically be updated (posted) to the ledger, when documents are printed.

You may disable this mode of document printing by selecting (placing a tick) in the “No print confirmation” field on Stock information (Setup ribbon). This will not print any documents when processing documents.
