Issue setting up printer

HP Recommended
macOS 10.15 Catalina

I just got a new HP ENVY PRO 6455 printer for college. I was trying to set it up today and ran into numerous problems. I took the printer out of the box and plugged it. I downloaded the HP smart app and after following the directions on the card the printer came with and on the app. Everything was going well until I tried to connect my computer to the wifi. The wifi at my school is a little tricky but I think my issue is with the printer or the app. When I first opened the app it found my printer right away. Then it told me to connect to the same wifi as the device I was going to use the printer with. I picked one of the wifi option but while it was attempting to connect I accidentally closed the app. At this point the printer was no longer purple like it said it was supposed to be to pair with a device. I restarted the app and this time it did not find my printer right away. I clicked the option to add a new printer and it told me connect to the HP-Setup wifi. When I go to my settings in the wifi there is no option for HP-Setup. I looked up other ways to manually set up the printer and nothing is working. I also have not been able to get the original purple light back that the instructions told me I needed to set up the printer. At the moment the light on the printer is white in the center. I don't know what this means or how to fix it.

I can certainly point you in the direction you need to go.


Printer communicates with lights - colors and changing patterns.  Pretty.

The first few pages of the User Guide explain what the printer is trying to tell you.

Way down on Page 110 is how to force the printer back to defaults so you can start over.
