PDF show great images but they print poorly--barely an image?

Hi,

Printer prints images well from other programs..

windows 7 64

Creating pdf from Chief Architect program, been using it for years.  Have all settings on highest quality I can find.  Went over everything with fine tooth comb. 

Any hints on how to make this work are welcome.  

Tried printing to color, gray scale, combinations of both, all bad. 

I think I had started using pdf creator from pdf995 because of the same issue with them.  Now I'm having it here.  Bummer.  

Thank you, 

Z
