Not really, other than:
*I don't think I've printed directly from InDesign—at all—ever—since giving up on it sometime in the CS2 era.
I suppose you'd have to weigh for yourself whether really getting to the cause of this is worth your time, when a simple workaround is already established. Could be InDesign, a corrupt font, a problem with the printer driver's read of the font, or any of those in combination.
It's kind of like putting a butter knife in the microwave. You can't really explain the blue lightning; you just know to avoid it.
