render print problem

Using nvidia render progam w. 2002. Part is rendered and looks great.
Then I look at 'print preview' and it looks like chicken screen. Is
there a setting somewhere than changes this? This never used to happen
so if something was changed..., I'm at a loss as to how to fix this. Any
help will be appreciated. Thanks, I hope....

 

I was using the nvidia render program that did print rendered views
previously. I have been 'print previewing' which is now showing up just
like the print, i.e. chicken scratch pattern. I changed something and
time has passed leaving my memory as to what actually I did change to
bring this about. Maybe NVidia support will help me if I ask them real
nicely. I've pulled out a couple old nvidia rendered prints and they
looked pretty good to my eye anyway. I recall 'print previewing' some of
these prints, as sometimes the print would split & print in two pages
or more if I had zoomed in too far. Thanks....
