I've printed your PDF on my HP Officejet 7000 printer and everything seems OK (see attached picture - IMG_0303.JPG). I also exported your PDF to JPG in Preview.app and again - everything looks right (attached "FRONT DOOR OPTIONS 1 07JAN2013.jpg").
The two things I've noticed in your PDF:
1. The stroke width of the lines in PDF are 0.000 mm - as Adibe Illustrator shows.
2. The color of hatch lines is light gray.
I think those factors could be the cause of your troubles.
