I've been having the same problem with a USB-connected Samsung ML-1740 on Kubuntu Karmic w/all recent updates.
Blacklisting usblp and "chgrp lp /dev/bus/usb/<bus>/<device>" helped (I can now print one document at a time), but after each successful print job, the job is shown as still pending and 'usb' process sucks 100% CPU until killed.
Please advise if you need additional help debugging.
