I'm sure there's no explanation for this, but it is weird. I printed this page, copying the single image on the right three times to fill the page. That turned out fine. Then I printed it on an HP C5280 all-in-one. The original image on the right is perfect, but the three to the left are weird. Look at the top.
It looks like PostScript errors I used to see when using third-party knock-off PostScript emulators in printers from the 1990s. I don't know what page description language HP uses, but that may be the problem.
