I have setup my HP Photosmart C4580 for wireless printing and scanning. But upon completion when it says "blah blah blah. You may now unplug the printer" and when I do it says it lost connection to the device. The printer works from the other 3 computers (1 desktop and 2 laptops which run Windows OSes). Am I disconnecting to soon (before pressing the finish button) or should I wait until after I press the finish button to remove the USB cable? I am using C.A.IN.E 3.0 if it makes any difference.

Are you using HPLIP to set up the printer? Please tell us more about what exactly you have done.

Yes I did use HPLIP. I have attached 3 screenshots of the setup process as well hopefully there is something there that which may be used to aid in this dilemma. I have used the auto installer and custom installer. I waited until the setup process was completed and pressed the 'Finish' button before unplugging the printer from the USB port. Last time I was unplugging the printer before pressing the 'Finish' button.

If the printer has an ip address, have you tried discovering it over the network? It's easier all around if you give the printer a static ip address and then ping it to make sure it's on the network. Once it is, I think you should be able to discover it like any other networked printer.

If you don't have the HPLIP GUI (hp-toolbox) installed, you can use hp-setup. If that doesn't find it, you can try passing the ip address of the printer to hp-setup with

On one of my machines, I did have to pass the printer ip to hp-setup. On the others, hplip has been able to find it without additional help.

My printer is wired, so I can't test this and I may be whistling in the dark.

I've done every possible setup scenario and nothing is working. Even tried the "code: hp-setup -i [ip address]" and the following keeps occurring:

I will try connecting the printer to the back of the router and set it up that. Hopefull that will work.
Thanks for your time, energy, wisdom and assistance into this matter.
