My pdf invoices are printing blank

My pdf invoices are printing blank

Whatever I do, I can not print pdf invoice properly.  I can see the invoices in the browsers ( Safari, Chrome, Firefox, Opera ), but any browser fails to print the invoice as a PDF properly.  Please let me know how to around this problem.

I'm using Max OS X Yosemite (version 10.10.1).  The attached image is what I see when I open the zoho invoice pdf file using Preview.  This image is the screen shot of the top part of the invoice where everything is blank but I see the total price near the bottom but nothing else.
