How to specify the DPI I want my Canon Pixma TS9020 to print at?

[jackm]

I want to print something at exactly 600 dpi but I can't find the option anywhere to change this. Can anyone help?

It is a confusing subject which is not made any easier by some apps. No matter what they say just remember you can't have DPI util you print. Think of DPI as Drops (of ink) per inch.
