Canon Pixma G1000 and 2000 do not have official drivers for Linux. So we need to install drivers from Gutenprint, or buy drivers from Turboprint. Turbiprint has excellent drivers which provide almost equivalent functionality as Windows. I said almost because they do not proivide a scanner utility or drivers. [Update: Scanning now works on Linux with sane drivers. Check my post.]

I’ll be installing gutenprint (available free) on Ubuntu Xenial.
Before proceeding, switch off your printer, and delete any existing non-functional drivers for G2000.
First add the following lines to your /etc/apt/sources.list if you dont have it:

deb http://jp.archive.ubuntu.com/ubuntu/ xenial-proposed main restricted universe multiverse 
deb-src http://jp.archive.ubuntu.com/ubuntu/ xenial-proposed main restricted universe multiverse 

Install required dependencies:

sudo apt-get build-dep cups-common gimp-gutenprint libgutenprint-dev

On official xenial release and a virgin sources.list, if you’re facing issues getting cups-common source to install, change your sources.list to the following:

###### Ubuntu Main Repos
deb http://in.archive.ubuntu.com/ubuntu/ xenial main restricted universe multiverse 
deb-src http://in.archive.ubuntu.com/ubuntu/ xenial main restricted universe multiverse 

###### Ubuntu Update Repos
deb http://in.archive.ubuntu.com/ubuntu/ xenial-security main restricted universe multiverse 
deb http://in.archive.ubuntu.com/ubuntu/ xenial-updates main restricted universe multiverse 
deb-src http://in.archive.ubuntu.com/ubuntu/ xenial-security main restricted universe multiverse 
deb-src http://in.archive.ubuntu.com/ubuntu/ xenial-updates main restricted universe multiverse 

###### Ubuntu Partner Repo
deb http://archive.canonical.com/ubuntu xenial partner
deb-src http://archive.canonical.com/ubuntu xenial partner

Now download the source release package (version >=5.2.13) from sourceforge or the git repo:

wget https://sourceforge.net/projects/gimp-print/files/gutenprint-5.2/5.2.13/gutenprint-5.2.13.tar.bz2/download
tar xvf download
cd gutenprint-5.2.13

Or:

git clone https://git.code.sf.net/p/gimp-print/source gimp-print-source

Now configure and make everything.

./configure
make 
sudo make install

After running configure, it should like this:

================================================================

Once make install is completed, switch on your printer. Ubuntu will show a notification that the printer G2000 was added successfully.

To get the scanner function working, install Vuescan, a paid software. Unfortunately, I wasnt able to get it to work with sane or scangearmp2. If you come across a non-paid solution, do share it with me.
I’ve now successfully got the scanner function too working with the help of the dev behind scangearmp. Check this post for details.
