I've done some reading but every setting I have read and tried has no change to this. My first 40 or so prints never had these lines. I took a break from printing for about 4 months due to family and work. Now I'm trying to print something for my wife and these lines show up. I even opened files that I have printed in the past and they too now have these lines. Am I missing something? Can someone lend a hand and please and thank you in advance.
