Hi, 

I've drawn a simple floor plan, when i export it to pdf everything looks normal. However, when i go to print, it prints with large black blocks over the drawing. I have tried changing my plot style and messing around with hatch scale etc. but nothing seem to work. I would appreciate it if anyone has any ideas on what the problem may be. I've attached  what my plans look like as exported and a pic of what they look like printed.  

Thank you
