Help in installing printer driver

[pensioner77]

Some time ago I tried unsuccessfully to install a driver for my Canon printer on my laptop running 9.10. I am now trying to install it on my PC running 10.04. The download appears successfully to my doenload file but whereas other downloads such as VLC & IBM Symphony then install by a double click,when I do this with the canon driver all that happens is Archive Manager opens with the following 5 entries:
cnijfilter-common_2.80-1.tar.tar
cnijfilter-common_2.80-1_i386...
cnijfilter-ip4500series_2.80-1...
faq-pd-2.80-1.tar.tar
guideip4500series-pd-2.80-1.t...
The files1,4&5 are shown as Tar archives and 2 & 3 as Debian packages.
Can anyone tell me,a distinct novice at IT, what I have to do next to complete the install?

If you don't want to deal with these files and install your printer's drivers the easy way (by using the package manager) run this command :

sudo add-apt-repository ppa:michael-gruz/canon

This will add this ppa to your repository list.

Now you can install the drivers with synaptic or in command line :

sudo apt-get update
sudo apt-get install cnijfilter-common cnijfilter-ip4500Series

Hope it helped

Thanks Demonipuch. it all seemed to be going OK until the last entry when the following showes E:Invalid operation installer. You mentioned the easy way using the package installer--that was what I had hoped to do?

Sorry there was a typo in the last command. The command is

sudo apt-get install cnijfilter-common cnijfilter-ip4500Series
