I did all of the above, including a 'deep' uninstall with a program called Revo-Uninstaller and re-installed,turned off anti-virus etc - BUT it looks like the problem is Net Nanny! which I arrived at by process of elimination,and it was recently installed on the problem laptop only. Printing is OK with it disabled. Do you you have any idea how to configure Net Nanny to allow the wireless printer to work? I have played with the settings and can`t find a way?
