The loss of the LPT1: port can occur on Windows 2000/XP when deleting the "Greatland Driver" printer driver when there were documents still remaining in it. The Greatland Driver was the name of the printer driver for previous versions of the software.

To re-add the LPT1: printer port, please Run the "LPT1Reg.exe" file from the link at the bottom of this article. When prompted, click on the Run option to run the patch. After the patch has been run, you will need to restart your computer before trying to print through our program again.
