"I've been trying to find a driver to make it work but I can't find anything, is it because Apple no longer supports it and can't make it work anymore?"
To update this tread I might seen answer to the original post! Some on Apple Dicussion found to look in System preference Privacy pane and find a driver for you printer and allow it to and this might work as before!
I'm sorry...but that makes no sense. Printer drivers don't reside in the Privacy pane. Maybe you could give us a link to what you saw?
In the case of folks who have upgraded to the latest version of the Mac OS, and their printers suddenly stopped working, sometimes the fix is to give the existing installed printer driver permission to access the "entire disk." But in the instant case for the OP, we are talking about a printer that hasn't been supported by the developer for 14 years.
