DFemul is the first and so far the only tool available on the Internet which enables emulation of fiscal devices. The emulator "pretends" to be POSNET compliant fiscal printers. It is used for testing software cooperating with fiscal printers.

The program is perfect for testing software for fiscal printouts, training in commercial and software companies and school education in the use of fiscal equipment. The principle of the application is simple. DFemul opens and listens to the RS232 port, to which we connect the COM of the computer with the tested software by means of an appropriate "cable".

Connect the two COM ports of the computer(s) using the NULL MODEM cable.
