I can think of one reason why this might not be implemented. You could
grab all the fonts off the printer that way. Since fonts do not enjoy
copyright protection in the US, printer manufacturers have to protect
their fonts by encoding them in proprietary format in ROMs.

Also, you'd need a fast channel like AppleTalk or a Centronics
interface for this to be practical.
