Here's how to get it to work. First, download the drivers from the canon europe website for the MP490. Select linux for operating system and download the RPM packages. Uncompress the tarball. One folder will be a website with instructions on how to install. The other folder will be the actual install script. Just follow the instructions and everything works great. It even sets up CUPS and everything like that.
The install program sets up default as well.
Now, does anyone know if you can scan over CUPS as well? Meaning, on my mbp, I can print using the CUPS interface to this printer using an IPP address. Is there a way to do the same for scanning?
