All PDF print as completely black pages. I can read the PDF fine. This is true on any printer.

By chance, did you disable automatic updates on your printer?  I am having this same problem.  It began after I disabled the automatic updates on the printer.  It happens if I use original manufacturer toner cartridges or replacement cartridges.

It does not happen if I print from Preview, only on Acrobat.

I did not have the option to print as image or an advanced printing option button to make any other adjustments but for me simply checking the box to print in black and white only fixed the issue. Luckily, I was not trying to print in color so this fixed my problem.

Still not answered...after 6 years??

I have the same problem, with certain PDFs, via a Windows PC, the pages print in all black. There is nothing wrong with the PC, driver, printer, software etc. because other PDFs print without any problems. I can't find a solution online, except the instruction to go to File>Print>Advanced>Print as Image. However, it is impossible to choose this option as it is greyed out. No other supposed solution works.

P.S. does it also happen if you print as an image?

Since you mention the registry, I assume that you are on Windows.

Are these local or online documents?  If online, on what browser?
