If the printer interface identifies the device as belonging
to the "USB printer" class, the device files will appear
automatically. The required driver (ulpt) is part of the
default system kernel.

In case it's not (for example when running a custom kernel),
add this line to /boot/loader.conf:


For details see "man 4 ulpt".

If the printer is not recognized with this mechanism, a
generic USB device (ugen) will appear. Some printer drivers
require this (instead of ulpt).
