To operate a new all-around HP Office-Pro-8500A (A910a) printer i'm currently running hplip 3.11.1.
have yesterday downloaded hplip-3.11.3a.run, as an upgrade which should now allow me to scan using the ADF (not available for this printer under 3.11.1).
Must I first uninstall 3.11.1 or can I run the 3.11.3a installer directly and hope it will automatically overwrite 3.11.1?
Thanks for helping.
