Hello William, this is Emily.
Indeed, this printer doesn't have a Windows 11 driver.
Unfortunately, driver is from the hardware manufacturer, not from Windows. Windows can only use what is available.
While there's no guarantee, sometimes an old driver, even not for Windows 11, might still work to get Windows to recognize the printer and do only basic features. It doesn't hurt to try the latest Windows 10 driver Dell has to offer anyway.
Just know that it is not a guarantee. https://www.dell.com/support/home/en-us/drivers...
