If your HP Printer cannot Print PDFs from Adobe Reader , then it means the issue lies in the Adobe reader itself. However, just to be sure, try printing any other PDF file from Adobe Reader and see if it prints. If the PDF prints, then the issue must be with that particular PDF you were trying to print. However, if you can't print any PDF file from Adobe reader, then follow the steps below to fix the program.
1. Restart your computer and open the PDF through Acrobat Reader once again.
2. Try printing the PDF file once again.
3. If that doesn't work, then you need to uninstall the Acrobat Reader and install it once again.
Your issue will surely get fixed once you will reinstall the program on your device. If the problem persists, contact HP Printer Support for help.
