Whatever was done to this tiff, it was weird.

Gimp wouldn't print to the printer at all.
gThumb printed out a solid black sheet.
Eye of GNOME would print it out, but in a very strange manner. Kinda stretched horizontally, like the old wide print mode on dot matrix printers circa DOS era.

Finally got around it by converting to PDF, then printing that. The job stayed in the print queue after completing, and CUPS shot up to 90% CPU usage and stayed there until I deleted the job.
