DESCRIPTION="HP Linux Imaging and Printing - Print, scan, fax drivers and service tools"
HOMEPAGE="https://developers.hp.com/hp-linux-imaging-and-printing"
# The Gentoo patchset is pinned to 3.26.4 on purpose: dev.gentoo.org/~billie
# publishes no 3.26.5 or 3.26.6 tarball (both 404 as of 2026-09-23), so 3.26.4
# is the newest one that exists. Three of its patches no longer apply to these
# sources; src_prepare drops them and reapplies their content from ${FILESDIR}.
# Revisit PATCHSET_PV on every bump: once a matching patchset appears, the three
# local patches below should go away rather than be rebased again.

# BENTOO-DIVERGENCE: PATCHES - three overlay-only patches. They are not new
# fixes: each one is a rebase of a patch ::gentoo already ships inside
# hplip-3.26.4-patches-1.tar.xz, which upstream Gentoo never rebased because it
# never packaged 3.26.6. dev.gentoo.org/~billie has no 3.26.5 or 3.26.6 patchset
# (both 404 on 2026-09-23), so this ebuild fetches the 3.26.4 one, drops the
# three members listed in BROKEN_PATCHES, and reinstates their content from
# ${FILESDIR}. Each replacement's header names the patch it stands in for and
# which of its hunks 3.26.6 made obsolete.
#
# This divergence closes the day ::gentoo bumps hplip, or the day a matching
# patchset is published - whichever comes first. It is not a permanent fork.
