Software protection

The software is protected against any unauthorized use by hardware key. The hardware key is an instrument which connects to the parallel or USB computer port. During operation, the software tests its presence. If the hardware isn't found, it will be automatically launched in the limited demo mode.

The hardware key can be used in local or network version. The local key has to be connected directly to the computer running the GROMA software. The network hardware key is connected to the so called license server, to which all the individual GROMA system installations connect.

The key can be connected to any LPT1 - LPT3 ports or to a USB port. The key is completely transparent for the standard printer signals, therefore it can be connected through this key. If you are using more keys connected in a cascade, and shall you have any troubles (some of the software doesn't work), try to change the key order, eventually divide them to other computer ports.

Important

The Windows based on NT technology (Windows NT, 2000, XP) do not allow for applications a direct access to the hardware; therefore it is necessary to install the driver for the hardware key in this operation system. The driver installation isn’t necessary in Windows 95, 98 and ME, but it can prevent the print conflicts. The driver is installed automatically during the installation of the GROMA system.

Important

For some types of printers using two-way simultaneous communication, the GROMA Software may not find the hardware key. In such case, it is necessary to install the hardware key's drivers, which are available on our website http://www.groma.cz.
