The "most helpful answer" from http://answers.microsoft.com/en-us/windows/forum/windows_10-windows_install/unblock-publisher-in-windows-10/acbf1b7e-64f3-4d14-aa81-837d121ce8e2?auth=1 tells what to try.
Can you confirm it works?
I have an HP Laserjet P1102W printer. I have a new Windows 10 laptop. I have not been able to use the printer with the new PC as I get a "This publisher is blocked" message when I try to load the printers driver. I've tried with the disk that came with the printer and by downloading off the internet. I did a quick search and came across a comment that maybe HP didn't want to pay some fees to Microsoft so MS has blocked HP software???? This can't be right, all HP printers cannot be used with newer Windows PC's??? Please help!
