Black boxes around images when printing

Some Mac users have reported that, when printing some of our pdf files, black boxes appear around the images, like this:

This seems to be a recent issue with the way Macs open and print pdf files.

Best solution:

If possible, please download the pdf file to your computer or device. Then open it with Adobe Reader, rather than Mac's Preview software, to print. 


You can try printing the page as an image. Choose File > Print > Advanced and then select Print As Image. Unfortunately, this will only allow you to print one page at a time, and the quality may not be as good.
