Comment 1 for bug 314106

Changed to Confirmed and setting release blocker for Jaunty as printing is a critical task.

Other users on Jaunty besides myself are also experiencing this problem, refer:

http://ubuntuforums.org/showthread.php?p=6935889

This is also occuring on Jaunty where On Jaunty. When trying to setup my samsung laser printer, the device appeared to correctly be identified and the appropriate driver installed. Users are able to change device preferences. However when actually trying to print, the job will stall at processing and the error message "(Printer Name) May Not Be Connected is displayed. No printing will occur.

I have run the apport sudo ubuntu-bug cups to hopefully get releated info to the devs for fixing.

From the info provided below, its clear that the system knows the device is on USB.
