Required Steps:
A. If you still have the source tarball go into the source directory--for example:
cd ~/Desktop/hplip-3.10.2
B. Execute this command to remove/uninstall HPLIP:
su -c "make uninstall"
or if your distro uses sudo:
sudo make uninstall
C. Enter the following command to remove the HPLIP installed directory:
*Warning*
If you do not enter this command correctly you could damage your system.
su -c "rm -rf /usr/share/hplip"
su -c "rm -rf /etc/hp" su -c "rm -rf ~/.hplip"
su -c "rm -rf /var/lib/hp"
or if your distro uses sudo;
sudo rm -rf /usr/share/hplip
sudo rm -rf /etc/hp sudo rm -rf ~/.hplip sudo rm -rf /var/lib/hp
D. The uninstall/removal of HPLIP software is now complete. Perhaps you would now like to re-install?
