To operate a new all-around HP Office-Pro-8500A (A910a) printer i'm currently running hplip 3.11.1.
have yesterday downloaded, 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.
