Good work. I tried to do similarly with a HP CP1025nw (roughly 10 years old), which has become unreliable with Windows 11. But although I connected the printer to the Pi (I used a model 3B) with a USB cable, CUPS does not appear to see the “usb://…” connection string. CUPS does allow me to connect to the printer wirelessly, with a connection string that begins “dnssd://…”.

So I have it working wirelessly but I was hoping to get it using USB since I suspect that would be more reliable.

I’m wondering why your Pi allows the “usb://…” method, but mine does not.
