Morphology
The printing sense is tangentially related to 'run' (as in operating a machine or producing copies) but the particle 'off' does not transparently contribute the specific meaning of 'make copies'. A B1 learner who knows 'run' and 'off' might guess an action involving a machine from context but would not reliably derive the specialized photocopying sense, so this is partially compositional but not fully predictable.
Etymology
Run off for liquids paints the picture of water running and going off a roof into the street or gutter. That's why it means 'to flow away' or be lost as waste.
