I have an HP ENVY 4500 e-all-in-one printer. It installed & prints successfully. But the scanner function does not work. Simple Scan says no scanner detected. I ran the command
sudo sane-find-scanner & the scaner was also not detected.
I tied upgrading my hplip driver to the latest version, but it fails with an error that GCC is not installed. But I know for a fact GCC is installed.
Any help would be appreciated.
