Installing the LPT device driver on Windows NT/2K/XP systems

The necessary device drive is in the lpt3ster.sys file. After having logged into your operating system with system administrator's privileges perform the following:

1. Copy the lpt3ster.sys file from the installation folder of the T3Ster software to %systemroot%\system32\drivers\
2. Import the contents of the lpt3ster.reg file (found in the installation folder of the T3Ster software) into the system registry. It is simply done by clicking the mouse on the icon of this file.
3. Reboot your computer to let the changes take effect.
