"PDE.plugin" will damage your computer or "HPDM.framework"
I have been using the same printer for years. The last three things I have tried to print, however, will not print. I am currently trying to print a mailing label that has been downloaded, but I continually get a message that the "PDE.plugin" will damage your computer or "HPDM.framework" will damage your computer. What's wrong and how do I correct it?
