Still a problem.
Arch Linux + HPLIP 3.22.10
Photosmart 5520
Photosmart 6520
At this point in time HPLIP does not include a quality settings value (gone ages ago), changing the .drc file does nothing (it's overwritten with the JPEG setting), xsane advanced settings includes only JPEG compression (no "none" option), and hp-scan --compression=none reports "error: Unable to set option compression to value None"
