Friend of mine running Ubuntu 8.04 on a new Dell Inspiron desktop. Bought a Canon Pixma IP3600 printer.

We found a driver on the Canon Europe web site.

Downloaded it, was a deb archive containing 3 packages:
cnijfilter-common_3.00-1_i386.deb
cnijfilter-common-3.00-1.tar.gz
cnijfilter-ip3600series_3.00-1_i386.deb

We double clicked on the first one above, it ran a package installer.

We double clicked on the second one the tar, it opened showing a bunch of files.

Double clicked on the last one and it ran a package installer

Now the printer works BUT resolution is limited to 600 and some features may be missing from the options.

QUESTION: What to do with the second file, the tar.gz. Where does it go what does it do?

We have no idea.

Help appreciated
