printer problem

Bought an older mac for one of my kids to do homework. Power PC G4 running Tiger. Installed printer driver for an Epson C88 printer from the Epson disk, went to system preferences to add the printer. Clicked on, "add printer." Nothing happens. Downloaded the correct driver from Epson website, installed the driver, same thing. I can't add a printer. Never saw this before. Everything else about the computer works. Connects to the internet via Airport and all applications work fine. Any help would be greatly appreciated.
