It doesnt. It says "Unable to open USB device "usb:/dev/usb/lp0": Success". Which I personally think is a bit of a scandal. And if you google for that, it turns out that URIs of this form are no longer supported, "largely because those device names are not stable [...]".

At this point I just uninstalled cups, and after some googling I installed lprng. It worked pretty much immediately.

I don't really know what the advantages of cups are and I don't think my experience entitles me to pass any definitive judgement. But debugability really isn't one of cups' strengths. A "printer fault!" error should produce some informative log output every time it is signalled. And yes, I had

LogLevel debug

in /etc/cups/cupsd.conf

I agree. :-)

Thanks for your help. Even if it didn't help me directly, it got me unstuck.
