Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Please tell me whether the lines appear in the same place on each page?
Also, please let me know, whether ordinary printouts, from a computer, lack those lines, or have the same lines, or perhaps different lines on them?
With this much information, I will be able to advise you as to what to do next. Please let me know, I stand by to advise you. Thanks.
