I am having a hard time figuring out a strange connection issue I just started to see on all my HP Color LaserJet 2600N, HP Color Laserjet CP2025, and HP Color LaserJet M451nw printers.
The issue is this:
The printer works and pings fine if you are printing or pinging it from the same subnet range that the printer is in, however if you are in another subnet range and try to print or ping that printer it will not work most of the time and then there will be a brief 1 to 2 minute window where the connection and pings start working again.
Changing any Networksetting on that HP printer will cause the IP address of that printer to be pingable again by the other subnet for a few minutes and then the issue returns.
Now the up and down of the connection to each HP printer does not match and each of the 6 HP printers connect are to different Dell...
