I just setup this exact printer on 2 Ubuntu 64-bit 12.04 desktops. Here's the documentation that I wrote, hope this also works on 12.10.

1. Go to the below link and download the Linux driver in ~/Downloads
   http://www.usa.canon.com/cusa/consumer/products/printers_multifunction/color_laser_multifunction/color_imageclass_mf8380cdw#DriversAndSoftware




2. Untar the tar.gz file downloaded at ~/Downloads/Linux_UFRII_PrinterDriver_V250_us_EN.tar.gz




3. Assuming that a 64 bit machine is being used, cd to ~/Downloads/Linux_UFRII_PrinterDriver_V250_us_EN/64-bit_Driver/RPM.




4. Create a symbolic link for 64-bit drivers:

   
   
   

   ln -s /usr/lib /usr/lib64
   
   

   
   
   

   (NOTE: There may be an existing lib64 directory there already and this will prevent the symbolic link from working correctly. Backup/move the directory to an alternate location before creating the symbolic link)




5. Install alien (if needed):

   
   
   

   sudo apt-get install alien dpkg-dev debhelper build-essential
   
   




6. Convert the RPM files to ".deb"

   
   
   

   sudo alien -k -c cndrvcups-common-us-2.50-1.x86_64.rpm
   
   sudo alien -k -c cndrvcupsuf2us-2.50-1.x86_64.rpm
   
   




7. Install drivers

   
   
   

   sudo dpkg -i cndrvcups-common-us-2.50-1.x86_64.deb
   
   sudo dpkg -i cndrvcupsuf2us-2.50-1.x86_64.deb
   
   




8. Go to System Settings -> Printing and remove the Canon printer (if it's there)




9. Click on Add and expand Network Printer. Select Canon MF8300C (IP_ADDRESS). Click on Forward and then Apply. Click Cancel on the test page screen.




10. Right-click the new Canon printer -> Properties.




11. Where is shows 'Make and Model' press 'Change'




12. Select 'Provide PPD file'




13. Navigate to /etc/cups/ppd/Canon-MF8300C-UFRII-LT.ppd and press Open




14. Select 'Use the new PPD as is' -> Apply




15. Restart the cups service /etc/init.d/cups restart




16. Test the printer.
