Comment 10 for bug 1442734

the LATEST version? I was hoping to avoid doing that, because I don't know how to undo all of it. Besides, https://bugs.launchpad.net/hplip/+bug/1448771 seems to indicate it might not work anyway. But since you asked, I have now run the installation, and then reinstalled my printer, and everything has succeeded so far, except one thing: after I had installed the printer via USB cable, I saw an error message on command line. It said "/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:127: RuntimeWarning: PyOS_InputHook is not available for interactive use of PyGTK
  set_interactive(1)"
Printing works though.

Thank you.
