i have an older s300 canon printer i've never had a problem with till recently. when i print out a picture or anything else there are straight lines running all through the background. i've done all the nozzle cleaning, alignment and everything else possible in maintenance and am kind of stuck. all this printer does is print but its been dependable. please don't tell me to get another printer. i already realize i might have to but this is a shot in the dark for some help. manual hasn't helped much. don't even know if you deal with printers in this forum.
