| Protocol | TCP |
| Description | The purpose of a mail box protocol is to provide at each site a standard mechanism to receive sequential files for immediate or deferred printing or other uses. The files for deferred printing would probably be stored in intermediate disk files, although details of how a file is handled, stored, manipulated, or printed at a site are not the concern of this protocol. |
