WIFI connectivity issues for Photosmart c4750 all in one printer

[Photosmart4750]

I moved across town and I'm trying to re-connect my HP photosmart C4750 back up (it was working fine before the move). I'm using the same internet provider, same computer, but different wireless router and modem. It seems the help I've been finding so far leads to a dead-end.

Hi,

What is your router brand and model? does it support WPS Mode?

Else, you would need to reconfigure the printer from your computer, what operating system do you have on your PC?

I have a tp-link system that I believe supports WPS Mode.

I'm running Windows 10 on my computer

Thanks for clarifying.

Check page 5 of its user guide below for steps to connect the printer using WPS, either Push Button or PIN, as supported by your router:

Please consult your router documentation for using WPS with the router, if there is any dedicated button or within the router interface web page.

Please let me know if you experience any difficulties,

I tried the WPS feature through my tp-link app and clicking the WPS feature on my printer, but when I do it comes back with an error.

I read another post on the HP site (that was talking about a different printer) that had issues if your network has both 2.4GHz and 5 GHz. At least in that printers case it wouldn't work unless the 2.4 & 5 were split on to two different networks. Could that be my problem?

That might cause a problem, separating the wireless band may likely  help, please give it a try and check, also make sure that your wireless security setting is not set to WPA3 which is not supported by the printer.

You may also try installing the HP Software by selecting a wireless connection, you will be prompt to temporarily connect a USB cable during the setup to connect the printer:

Please let me know if that works,

I don't know if I can locate that cable (haven't used it in years - and just moved so it would be packed somewhere). If I did find that cable, would that solve the problem if it were connected directly (wired) to my computer and eliminate the need for wifi?

It's sitting a couple feet from my computer, so if that would work, wifi wouldn't really be needed.

And I wouldn't need to go about trying to spit the wireless band (that I don't even know how to do).
