I just installed 12.04. I have a Canon MP970, which it recognized. However, all my programs print at 300DPI Draft. I want to change that to 600DPI Draft. I can do it manually but it isn't sticking and I have to do it every time.
I ran system-config-printer and changed the resolution, but it isn't flowing into my programs (gedit, LibreOffice, document viewer, etc.), even though the change does stick.
