Have you tried just cat dmesg or something similar directly to
/dev/usblp0 to see if the printer is working? If you get printing from
this then . . .
One possiblity is that lp isn't working properly, I'm not an lp user so
I won't be able to say much other than that I like CUPS. Have you
checked /var/log/lp-errs for any usefull information from lp?
If it doesn't print something then it's going to be harder to debug.
