Have tried everything I'm aware of so far. Any ideas welcomed!!!
Check your firewall settings. I had/have the same problem, but it is a firewall access issue. There is a "allow - deny" window that pops up for about 3 seconds, and if I am fast enough to click "allow" before the window goes away, it prints. If It goes away before I can click, it hangs forever and I have to delete the print job and start over, with my mouse ready to quickly click the allow button.
I have checked my firewall and the printer is listed there to allow incoming connections. So, I don't know what is going on.
