Not bad for an interm solution. Debian already has 3.18.10 packaged, and
based on their versioning scheme it still contains non-free artifacts.

Here's what I have right now:

;; Delete non-free blobs$
(delete-file "prnt/hpcups/libImageProcessor-x86_64.so")$
(delete-file "prnt/hpcups/libImageProcessor-x86_32.so")$
(delete-file-recursively "prnt/plugins")$
(substitute* "Makefile.am"$
  (("dist_printplugins_DATA") "# dist_printplugins_DATA"))

and a patch from debian to address imageprocessor:
  https://salsa.debian.org/printing-team/hplip/raw/debian/3.18.10+dfsg0-1/debian/patches/0025-Remove-all-ImageProcessor-functionality-which-is-clo.patch
