I have suddenly gotten this bar through my exported PDF map and when I print the map. I doesn't appear in print preview or in the view. I have attempted to change the printer settings for PDF and the printer, however it doesn't change anything. Any suggestions would be very helpful.
Is it possible for a layer that is hidden to be set for print only.
If not, here are a few possibilities that you can try:
