Ok. After group installing Fedora Workstation edition onto my laptop, I was able to actually simulate a little of what you are going through. Here are my screen shots of what I did.
This first picture is before the driver install of the printer driver database.
This next picture is me double clicking the zipped file. Then opening the new file in a new window. Then right clicking and opening the file in a terminal. Then typing: ls , to see what is in the file. Then running the install by typing: sudo ./install.sh
This is the printer driver database after the install.
If your printer doesn’t work after this, then it isn’t a driver issue. It is a font issue or something else.
