xPrint FirstDoc is a program for automation of accounting and barcode printing on payment documents. The application installs a virtual printer "xPrint" in the system, which prints the barcode on the payment documents. It is possible to save the generated documents for transmission by e-mail. The program works from the system tray. The barcode parameters are configurable. In addition, xPrint FirstDoc can act as a gateway between the Client-bank application and the accounting programs.
