It is an Epson Stylus C43 series. The printer has worked find as a wireless printer in the past. My drivers are up to date. This a metter of allowing my personal PC to access this printer via the new security code. Another PC can access it fine (as before) using the new security code. The security code was added to her PC via AT&T. A physical Ethernet connection should not be required. I think it s a matter of how to enter the new secuity key and associate it with my OPC.
