Canon drivers printing broken in Natty Narwhal, 11.04

I've been using the Canon drivers for printing on my Pixus MP540 and IP4500 for a couple years now, but now trying to print on either using those drivers results in failed printing. For the IP4500 I was able to switch to GutenPrint drivers which make it work, but unfortunately there aren't open source drivers for the MP540. On attempting to reinstall the MP540 drivers, I get the following package errors:
$ sudo dpkg -i --force-architecture cnijfilter-common_3.00-1_i386.deb
[sudo] password for theron:
dpkg: warning: overriding problem because --force enabled:

These are the versions of the problem packages:
$ apt-cache policy libc6 libcupsys2 libpopt0

Evidently the system packages are too new for the Canon deb files? Is this a simple matter of creating some soft links in the /usr/lib directory, or do I need to downgrade the system files to a version that will work with the Canon drivers? I checked the Canon drivers here: http://software.canon-europe.com/products/0010641.asp and their last release (3.0) was 04-12-2008, so I'm working with the newest version of their files available.

Thanks for your time and consideration. I'm looking forward to hearing back.
