[Please don't top-post, it makes replying harder.]

Some inexpensive printers don't auto-switch ports, so try disconnecting 
the parallel cable when testing USB.

If you have lpd_enable="YES" in rc.conf, you don't need to start lpd 
from the command line.

There should still only be one running.  Is the second one grep, maybe?

Check the status:

% lpc status lp

And try restarting the printer:

% lpc restart lp
