Operating System: macOS 10.15 Catalina

The message about HPDM.framework kept coming up on my iMac screen when I tried to print a document. I used Finder to locate the file - it was actually a folder. I dragged it to the trash and emptied the trash. Then I couldn't print the document. I went to HP and started to reinstall the printer software.  Halfway through installation, the message reappeared and the installation stopped. I found and trashed the HPDM folder and the installation stopped. After a while, it continued and when completed, the printer works. However, every time I print a document, I get that HPDM warning appearing. I hit the "OK" button and a different message comes up - "Matterhorn framework" will damage your computer. I "OK" that one and the printer finally prints. I can only assume that from now on, I'm going to keep getting this two messages every time I print something.
