"PDE.plugin" will damage your computer

I have an HP Laserjet 1012 and I'm running Catalina 10.15.4.

I also received the message about the PDE.plugin

I did the following:

1) I went to System Preferences > Printers & Scanners and deleted my affected printer.

2) Went to System Preferences > Software Update and installed the HP printer update.

3) Went back to System Preferences > Printers & Scanners and re-added my HP Laserjet 1012.

The only issue is what to do with the PDE.plugin file which still shows up in the finder.

Here is the fix for the odd problems with HP printing after the Catalina 10.15.7 update.

Go to System Preferences -> Printers & Scanners. Delete the HP Printer.

Go to your HD -> Library -> Printers. Delete the hp folder.

Reconnect your HP printer.

Go to System Preferences -> Printers & Scanners. Add the HP Printer.

System will auto update the required HP driver software.

You should be all set, as it was for me.

Good Luck.

I reset the printing system and it resolved issue . SystemPreferences, then click Printers & Scanners. Press and hold the Control key as you click in the list at the left, then choose “Reset printing system” 

Prior I did try safe boot,removing and adding printer several times,adjusting advanced settings and it didn’t resolve issue.

If this is your only printer, in the printer settings the System Preferences, right click under the list of printers and choose, Reset printing system. This will clear all printer setup data, though I'm not sure if it will remove the HP subfolder from /Library/Printers/. If not, you can manually move that folder to the desktop.

Once done with those steps, install the new drivers. Then add the printer again.

Apple and HP have recently posted their own possible solutions.

If your HP printer doesn't work and you see a warning that HP software '...will damage your computer' - Apple Support

Within that page is a link to HP's page.

My guess is HP's uninstaller trashes the entire hp subfolder in /Library/Printers/, which would remove all of the now broken driver components. You then reinstall the drivers from the newer, working installers.

This is something I thought of mentioning myself before these pages existed, but was not keen on sending inexperienced users into the Library folder to delete things.

problem solved. re-installed the driver.

Hi There, I had same problem. Delete your printer then, download the apple update and re-install

I had this problem with an HP Deskjet D4200. Downloaded the latest drivers for Mac OS X. Completely solved the problem!

I had this problem with OS Catalina - upgraded printer drivers and the problem went away. Good luck!

To Mick Guinn, thanks for advice. I found a solution by uninstalling the printer then reinstalling and the annoying PDE.plug-in message disappeared and printer is printing once again.

Caused after HP unintentionally deleted a driver certificate.

Solution:

• Delete the printer
• Reinstall HP software from Apple - https://support.apple.com/kb/DL1888?locale=da_DK
• Install printer
• Problem solved 👍🏼

Enjoy your day 😉

I had the problem, cleared the printer from my laptop, shut down de powered both laptop and printer counted 10, powered up the printer then the laptop, loaded the fix software from the forum fix. Opened the package and waited until it was activated selected a document and sent it to the printer and it worked and has continued to work. Good luck.

A solution, although it is a multi-step! https://www.youtube.com/watch?v=AMUFffT73Vw

deleting my printer and then adding it does not work for me. I haven a hp l7600 device. when I add my printer it directly gives the message "fax.backend" etc.. and Lateron "hpdrivercore.framework" a few times.
