Q: how do I remove old adobe PDF printer driver (OS X)

A long time ago I had Adobe Acrobat 8. The application is long since off my drive, but I still have a persistent Adobe PDF 8.0 option in the "Add Printer" window of Mojave's Printers & Scanners Preference Pane. I've searched and trashed obvious culprits (in /Library/Printers/PPD Plugins) but it remains. I don't have an uninstaller for Acrobat; how do I get rid of it?
