Surprisingly, installing an HP ScanJet G4010 Scanner in CentOS 7, was easy.
Which is odd, as you would think it would be complicated.
After wiping and re-installing CentOS7 on my workstation, I realized that you have to have the EPEL Repository installed, prior to following the instructions listed below.
We just have to install one application, and there is no command line involved:
Applications System Tools Application Installer Categories : Graphics Simple Scan Install
Then plug in the scanner and turn it on.
Oh, Linux! *tsk*tsk* Setting up a printer – ridiculously complex. Setting up a scanner – ridiculously simple.
