Bug#630228: Info received (Bug#630228: foo2zjs: Firmware upload is not compatible with cups)

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

The fix is simple. The firmware uploader script needs to determine 
whether usblp is loaded or not, and if it is not loaded and the CUPS 
filter /usr/lib/cups/filter/usb exists, it should run a command line 
like this ("1020" replaced by actual model number):

for uri in `sudo /usr/lib/cups/backend/usb | grep -i 
'HP.*LaserJet.*1020' | grep -v FWVER | cut -d ' ' -f 2`; do echo $uri; 
sudo DEVICE_URI="$uri" /usr/lib/cups/backend/usb 1 1 1 1 '' 
/lib/firmware/hp/sihp1020.dl; done

This goes through all devices of the given model which do not have 
firmware loaded yet and load the firmware into them using the "usb" CUPS 
backend. As the usblp module is blacklisted by the CUPS package, this is 
sufficient to solve the problem.
