Trying to enter my SSID password from the printer, I'm unable to find the "$" character.

We can use the USB connection and convert it to wireless-

Change the connection type with the HP Printer Setup & Software utility or with the HP Smart app for Windows 10. Leave the USB cable connected until you are prompted to disconnect it.

Convert your USB connected HP printer to a wireless connection in Windows.

• HP Printer Setup & Software utility: Search Windows for 'HP', and then click the name of your printer in the results to open HP Printer Assistant. Click Utilities or Tools in the top menu bar, click Printer Setup & Software or Device Setup & Software, and then click Convert a USB connected printer to wireless to launch the utility.

  Figure : Convert a USB connected printer to wireless utility in HP Printer Assistant

  

Refer to -Changing from a USB to a Wireless Connection

Hope this helps!

Let me know how this goes!

I searched for Printer setup and software and found this to download OJ_AIO_4500_G510a-f_NonNet_Full_Win_WW_140_408-4.exe. I ran it and then went searched Windows for HP and showed me Add your first printer. Nowhere to enter my printer. What am I missing?

You have not installed the full-featured drivers on your computer, let's install them first-

Connect via USB and complete the installation and then convert it.
