# Forget it folks - this ImageProcessor closed-source blob is broken, and there
# is no way to fix it. We will use this patch from Debian to remove it from
# hplip, reverting to the way things worked in the 3.18.6 release. If HP ever
# sees fit to make ImageProcessor mandatory, we'll likely stick with the last
# hplip release that can be made to work without it, and any HP printers that
# require a newer version of hplip will not be supported.
