communication following the conventions defined by the NPA protocol.

Auto is the factory default setting. Auto sets the printer to examine data,
determine the format, and then processes it appropriately.

When set to On, the printer performs NPA processing. If the data is not in
NPA format, it is rejected as bad data.

Changing this setting from the printer control panel and then exiting the
menus causes the printer to restart. The menu selection is then updated.
