Please help. My laptop was working fine. Then I took it to a conference and interfaced with the local system using an ethernet cable. Now I am back home and cannot print either wirelessly, which I had been doing, or plugging into the printer directly with a cable. When I try to print I get a message “Locate cdintf~1.dll. “ I tried looking up the message on the internet but it doesn’t make any sense to me. Any suggestions as to how to restore printing capability? Thanks, Louise
