Just joined the MAC family and so far liking it. However, I did not give up my PC laptop, at least not for awhile. I move my IP4300 Canon printer over to Airport to get full access in my house. It all works fine except I get a message on my PC laptop that it is having a problem with bi-directional communication and telling me to enable it on the printer. There no such setting that I can find, and believe that it is only to have the ink level status show on the laptop when printing, as the printing part works fine. Anyone experience this and/or have a solution? Thanks in advance.
