General Advice about Computer Ports: Serial. Parallel. USB. and Network
In Tiger mode (also called "Embosser mode"), the embosser works entirely through Windows. You cannot use Tiger Mode on an MS-DOS only computer.
First, cable your Tiger to your computer with the parallel cable. Next, install the Tiger software (either a CD-ROM or from the ViewPlus website).
To see if everything is working, use Run Program. ViewPlus. Toolbox. Test Program. You should get a sample page of output on the Tiger.
On DBT, it is vital that in the Global Embosser Settings you use a Left Margin of 1. If you do not have a Left Margin, you might lose the first character of each line of braille.
