You cannot do driverless printing (IPP Everywhere) through a classic USB 
interface (usb:/... or hp:/...). You need an IPP network interface or 
IPP-over-USB.

Either connect your printer via the network (Ethernet or Wi-Fi) or make 
sure that ipp-usb is installed, the ipp-usb package of your 
distribution, the ipp-usb Snap (https://snapcraft.io/ipp-usb) or ipp-usb 
from source (https://github.com/OpenPrinting/ipp-usb).

Done that, run the command

driverless

You get one or more URIs then. Only these URIs can be used with "-m 
everywhere", as these use the IPP protocol. Any other URI will not work.

If no URI is listed (or none for the printer you want to set up), you 
either did something wrong or you are out of luck (old-fashioned printer 
which NEEDS a driver). If a URI for your printer is listed, use it and 
you get a working print queue.
