TurboPrint & PrintFab

I have done nozzle checks, also head clean and strip out and clean all before doing my original post. I have also done a head alignment. If I print from F spot then I do not get the lines on the photo but get a low res. print. The lines that appear on the photo look like a ploughed field pattern. Us...

I have installed turboprint but the quality of my print from gimp is still showing lines across the print. The same printout from ms windows using the canon drivers shows non of these tramlines. Anyone any ideas of how to fix this problem.
