Bug#663868: Blacklisting usblp helps

[Till Kamppeter <till.kamppeter@gmail.com>]

Please remove the blacklisting for usblp, run

# modprobe usblp

set CUPS into debug mode:

# cupsctl LogLevel=debug

and then turn off and turn on the printer again. Does it load its 
firmware? If not, attach your /var/log/cups/error_log file.
