To be more precise:
When IPP is being used for transporting a message (document, print
instructions) from a willing sender to a willing recipient, alignment
with other widely implemented and deployed Internet protocols for
message transmission (mail, fax, Web) is more useful than alignment with
some hypothetical and not widely deployed protocol for system management
and monitoring of the status of a device.
