No, that won't help unless all you care about is the print data, in
which case a port monitor might be the simpler approach; put it in
/usr/lib/cups/monitor and then use:

     lpadmin -p printer -o port-monitor=foo

to associate it with the queue.  Port monitors use the same filter
interface as everything else...
