Using Ubuntu 12.10 on my laptop I also have a Canon Pixma MG 3200, which is connected wirelessly to my router.

I don't really need extra drivers for printing since I can simply add a printer through the "add printer" dialogue in system setting/printer and choose network printer and then the older 3100 model.

So far so good. Now I also want to use the Pixma's scanning ability. How do I do this? Thankfully Canon provides Linux drivers here:
Printer
Scanner

(clickable links above)

I downloaded both and managed to extract the archive, creating two new folders (packages & resources) as well as a install.sh file.

I tried to run the install.sh and something happens, but it vanishes too fast for me to see whether it's an error messages or not. Nothing else changes.

My question: What exactly (I am very new to this) do I do with this file?

I understand that once the scanner driver is installed it should be recognised when using "simple scan", right? Right now it doesn't.

Thank you for reading and if you could give me a hint I'd be grateful.
