Title: usb printer works intermittently after upgrade to Precise Status in “cups” package in Ubuntu: In Progress Bug description: I have a Canon MF4150 mono laser printer...was in use on Oneric with no problems. Testing Precise (12.04) on another machine before cutting over & found printing problems with this printer. Tried to research the issue but have not found a fix. When first powered up, the printer works fine initially. After a few jobs, it stops working. It appears that after the last successful job, the printer is left in a hung state...visible evidence is the "Processing Data" indicator on the printer remains on...forever. In normal operation, this indicator goes off immediately after the last page of the job is completed. Once in thsi state, the printer never prints again until power is cycled. However, while in this state, Cups still appears to send print jobs, but nothing actually prints. The cups log indicates that cups is sending data to the printer in a sequence of transfers (8192 bytes each). So cups apparently thinks the printer is accepting the job. I've compared the log sequence for jobs that print and jobs that don't and I can find no difference in the information reported in the cups log (at full debug level logging). The problem is unlikely to be related to drivers since the printer is operating in raw mode (the machine is a samba server for Windows printing clients). Have tried uni-directional constraint suggested in various places. This printer does not work at all if this option is applied. I have tried blacklisting the usblp module. This does not solver the problem. Since it does not happen every time, it seems related to the sequence or timing of usb transactions. Were there significant changes in usb behavior that would have affected raw printer handling between Oneric and Precise? Need to move forward from Oneric...printer testing is my last issue. Help would be greatly appreciated.
