I running Windows 7 Home premium sp1. When I installed my Canon Pixma iP4950 I find that the printer cannot be communicated with, problem is the enable "bi directional support" button is greyed out. Canon seem to think it is a Windows fault. I'm waiting on Microsoft for an answer. All help greatfully received. Thank you.
