Here's a hack Jan-Espen Pettersen (sigsegv at radiotube.org) posted on 
FreeBSD-Questions which solved the problem:

---- START
I found that the usb backend stalled here before actually doing any
work. Before I've done any actual debugging of the backend, I suspect
that it is being blocked on a status read attempt, though this is only
my current guess.

Here is a workaround:

In printers.conf () you will probably find a line like this:

DeviceURI usb:/dev/ulpt0

change usb: to file:, so that it looks something like this:

DeviceURI file:/dev/ulpt0

Then restart cups. Cups will not read any status information from the
printer, but at least it can print. Be warned about unknown side effects. :)
---- END
