Dell E310dw XPS Software is Bad / Missing

I have a Dell E310dw XPS monochrome printer. Wanting to know the status of my toner level, I searched my Start Menu for an applicable application. All I could find was Dell Document Hub, and it said that A) There is no printer installed, and B) There is no default printer. Huh? I opened up the Devices and Printers applet of the Windows 10 Control Panel, and the printer is right there...and that it is not the default printer.

This is absolutely ridiculous. Dell stopped supporting this printer in 2018, before I purchased it. Does anyone have any idea how I can remedy this situation? It is an excellent printer, but I'd kinda like to know when I need to buy more toner, and I don't know how to tell Windows that the only printer is indeed (Duh!) the default printer.
