why does publisher sometimes leave phantom lines on my document?

[Jrauth]

Sometimes when I will be printing a publisher file I will find a line on my
copy that is not seen on the screen, why is this? And what can I do to fix
this? I work at a printing business so we would like a more effective way to
avoid the lines on our customers documents. Otherwise we just go over them
with white text boxes. Although this is not always effective because then the
line just moves.
Thank you, I appreciate your advice.

My printer will do this sometimes depending on the size of the publication. HP
advises using a higher resolution setting on the printer. This worked for me.
