This may seem like a rudimentary question, but I wasn't sure where else to ask it. I've set up some QoS rules on my router that give the highest priority to all traffic incoming and outgoing to my computer's network address, and it has so far done an excellent job of preventing lag and communication issues while someone else on my network decides to watch netflix.
An unfortunate coincidence - which I now believe to be a side effect - is that my HP 6980 printer refuses to communicate with my computer to print. No one else on the network has the same issues. I have attempted to reinstall the printer multiple times without success. In the settings, the printer shows the correct information and even the ink remaining, but will not communicate when trying to print something.
Could my QoS settings (set up with very minimal knowledge) have removed my ability to print wirelessly? If so, how might I go about fixing it?
