Printing PDF's , elevations, cross sections have a solid black background. Perspective camera views also have a solid black back ground and a black grid over the picture. I am using Apple , X 13 and a new HP 7740 printer ( my faithful 12 year old Brother MFC6490CW is not the culprit as I thought )
Reading articles on this subject in the Forum - the cause is linked to transparent backgrounds? using Apples' preview app?
The print shops I have sent PDF's to - not a problem -
As suggested I upload Adobe app and printed though it. -- same issues . Any suggestions how to use a white background instead of transparent ??
I have started a a case with Chief Tech support - will share their response
