if you look in the Wordstar directory/folder there is a program WSINSTALL or similar. This is used to install *AND/OR* configure Wordstar.
If the printer drivers were not optionally copied to the hard disk during installation, you will need the Wordstar delivery disks (possibly 2) containing the drivers.
Please advise back on progress.
As a matter of interest, where are you located? I am in Hammersmith,West London.
Good Luck - Keep us posted.
