Hi there and welcome
Did you recently receive a new wifi modem? Or what actually changed in your environment?
Please let me know.
ok, your able to use it wirelessly?
ok, connect it to your computer and run the installation again.
During the installation it will ask you to add it to the wireless network, say yes and complete this.
Then ensure that you can print wirelessly.
Once done, then on his computer, go to the apple symbol in the top left, then system preferences, then printers.
Click on their printer and remove it.
Then click on the + and allow the Mac to find it on the wireless network, then click on it to install it
Once done they can print wirelessly
Let me know how you go please
ok, you do not so it manually, but you will see the option to automate it.
You must be missing this, can you do it again please
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
yes, that is because your trying to connect to one on the network, you are setting up a new printer and you need to choose the option please to connect a new printer to the network, not connect to an existing one.
in step 1 uncheck custom install please.
no, it is checked, you see it in your screenshot.
Your choosing to connect to an existing printer on the network, but it is not on the network so this does not work.
Please repeat and uncheck custom install
ok, I just checked as I only took your word about the wireless when you said this, but this printer is not wireless, hence the issue
You need to connect it via a network cable to the internet modem, then do this installation.
But you have it connected to your computer via USB right?
Disconnect the USB to your PC.
Connect the printer to a different LAN port on the modem then run the installation again please, not checking custom
Tell me if it then finds it please.
can you remove the power to the wifi router please and wait 5 minutes, then connect the power to it, and then try to add it
Let me know the results please.
