I recently upgraded to 14.04 with cndrvcups-common and cndrvcups-ufr2-us 2.80-1. When I print a test page or PDF from evince (and presumable other print modes as well), /usr/bin/cnpkmoduleufr2 cpu use goes to 100% until killed (at least 15 minutes). This used to work in 13.10 with 2.70. (I suspect this is a problem with the driver and has nothing to do with the ubuntu upgrade.)

strace shows apparently endless repeated lines like this:

read(7, "", 4)                          = 0
read(7, "", 4)                          = 0
read(7, "", 4)                          = 0
...

Before I invest time on trying to recompile cndrvcups from scratch... does anyone have this working or at least have the same symptoms?

I contacted Masayuki Sakura at Canon, the maintainer listed in the Debian package. His reply:

We were able to reproduce the same kind of problem as the issue you reported. ... could you install 32-bit version of libstdc++6 with the following command and perform print test.

# apt-get install libstdc++6:i386

By the way, I have checked our user's guide and readme file, but this notification is not described. We will add this notification to the next version of the driver.

Indeed, this solved the issue.

Thank you to Masayuki for his prompt customer support.

I just downloaded and installed the Linux_UFRII_PrinterDriver_V300_us_EN drivers from Canon's website and my mf4890dw printer is working now. I could not get it to work with the V280 drivers, but the newer V300 drivers do work!
