The printer does not disappear.  CUPS says that it cannot access
/dev/usb/lp0 (or whatever name it seems to take - at the moment the
URL is usb://HP/Laserjet%20HP1300, which I did not assign).

I don't ever (well, rarely) switch runlevels.

Let us hope so.  Not being able to modify, delete, or stop a printer
is annoying, to say the least.
