After updating to Big Sur, one of my three Mac Minis doen't recognize my HP6980 LAN-printer (neither on WiFi nor ethernet). It thinks it is a PCL-laser printer. Duplex recognized but it only prints black/white (status color cartridges not shown). The other 2 Mac Minis have no issues. How do I try to fix this?

Edit 20 dec 2020: The Mac giving the issue has a driver version 2.3 The Macs without issues have driver version 4.0.5. Even after "forcing" BS to choose the correct deskjet instead of the PCL-laser the wrong driver persists.
