I'd call it a bug in the printer that it continues to indicate
online when it has lost its connection to its host (unless it
also has a network connection, and in that case I imagine you'd
be using the network instead of USB).

Now _that_ sounds like a possible bug in the USB subsystem, since
USB is supposed to be completely hot-pluggable and should not need
a reboot to get itself straightened out after a mishap.  Cc-ing usb@
list.

One question which will surely arise is, which FreeBSD version are
you using?  The USB stack was completely rewritten in 8.0.
