Mobile Printing & Cloud Printing

I have an HP 3755 all-in-one printer. Since late last year it has been printing black ink like bubble letters. Just outlines with no filling. For the longest time, I printed in color and didn't fix it. Today I decided to try to fix it and none of the recommendations I could find did anything. So I gave up and did a factory reset. Now I can't get it to connect to the internet. I tried like 7 different things I found in the printer guide and online until I found a video explaining that I should re-add the printer to the HP Smart App.

Enter the subsequent frustration. I get the app to locate the printer and then tap Continue to have the app find networks to connect to. Then I just get a spinning circle of doom that will spin for an hour and disappear. I've uninstalled and reinstalled the app, I've stood next to the router, I've turned things off and on and nothing works. It just never finds a network. I am completely at my wit's end and about to throw the printer out the window. Please someone tell me they have a way to make it work. And before anyone suggests it, yes I have to use my phone (Android 13) because my only computer is work issued and I cannot install my own software onto it.
