I have a problem with my plotting.  All my other sheet layouts print properly aside from this one.  When I view my drawing in sheet layout, everything is fine including the contents of my viewports and even in print preview I see everything is perfectly fine, but when I see the final printed sheet, some lines are missing. I sometimes use batch plot sometimes.

The layers are fine. everything is printable. 

I don't know the solution. please help.

Thank you!
