I am using Ubuntu 8.04 (Hardy Heron) with the latest xsane installed.
But I have also used a driver from OpenPrinting.
Here is the link to the site that has the directions to install the driver in Ubuntu. I have linked this paragraph so that you can verify the code.
Add the line to your /etc/apt/sources.list file
And then run
Once you do this go into your printer configuration and add a new printer - it should find the following driver:
sudo apt-get update
Epson WorkForce 600 - CUPS+Gutenprint (OpenPrinting LSB 3.2) v5.2.2
That should do it.
If you have any questions let me know - if I do not know the answer I will help you find one
BTW - I have never really posted codes before so I am not sure if I have done this properly (that is why I have included the link to the directions).
Hope this helps!
