Error code 9672 when adding an EPSON C120?

Like a lot of you, I have been frustrated with an error code that seems to be prohibiting me from adding my EPSON C120 printer to the printer list. I have spent extensive time talking to EPSON Support. I have checked and rechecked the cables. The printer is brand new and printed for about a day and a half. Then, then next time I needed to print was a week later, that is when I started having problems. It started as a Communications error message, I fixed that with clearing up some memory. Then the print jobs would be stopped automatically. In trying to fix that (Epson suggested uninstalling/re-installing) now the computer will not let me add the printer to the list. I am not trying to run the printer off an airport, it has always been plugged into the back of the computer. Does anybody else have any suggestions in order to solve this problem, please?!?
