Glad I came across this. I am checking out the trial and planned on buying it after it is over. Now I am not so sure unless this problem can be solved. I pin pointed it down to AdGuard since it was the last thing I installed on my pc. When I go to print. It will not print and give me a error. It also mentions the device not being connected. Even though it is and showing on wireless. When I closed AdGuard and ended the service task for it. Printing resumed fine once again. Printer tools etc as well. So, AdGuard is blocking something causing my printer not to work. Anyone have a solution? Windows 8.1 64 bit.
