To print a copy of an Invoice, a Receipt, or some other record of a transaction to a file on the system's hard drive, specify the Printer on the Print Buttons Form screen that is configured to print to file by having Printer Driver set to Plain and Port set to File.
On the Printer Output Port-File settings screen, enter a file name and optional path. The name and path must be in standard Windows format. Long file names are supported.
