I'm having a problem installing this on my machine using Ubuntu 11.04, AMD64. I have a Pixma MX320. I tried following these instructions, but i'm getting package dependencies which are odd:

alan@devserver:~/cnijfilter-mx320series-3.10-1-i386-deb/packages$  sudo dpkg --force-architecture -i cnijfilter-common_3.10-1_i386.deb 
dpkg: warning: overriding problem because --force enabled:

then when i tried to apt-get those, i got the response that they were all up to date:
alan@devserver:~/cnijfilter-mx320series-3.10-1-i386-deb/packages$ sudo apt-get install libc6 libcupsys2 libcups2 libpopt0

Note, selecting 'libcups2' instead of 'libcupsys2'
libc6 is already the newest version.
libpopt0 is already the newest version.
libcups2 is already the newest version.
