Boeing pays at least on business I know to essentially have a complete label printing line with staff available to run it. Each label must be hellaciously expensive when they need one but my understanding was that some(all?) are part of the certification for airworthiness. So a missing or damaged label can ground the plane, which is far more expensive than the label.
