(3) With the "application/postscript" content-type, the remote
printer server should evaluate the contents in a safe execution
environment.
(4) With the "multipart" content-type the subordinate contents will
be processed recursively: for a "multipart/mixed" or
"multipart/digest" content, each subordinate content will start
on a new page, whilst for a "multipart/parallel" content, all
subordinate contents will, if possible, start on the same page.
Naturally, when processing a "multipart/alternative" content,
only one subordinate content will be printed.
When the remote printer server finishes its processing, a message is
returned to the originator, indicating either success or failure.
2.1. Naming, Addressing, and Routing
A printer is identified by a telephone number which corresponds to a
G3-facsimile device connected to the international telephone network,
e.g.,
+1 415 968 2510
where "+1" indicates the IDDD country code, and the remaining string
is a telephone number within that country. This number is used to
construct the address of a remote printer server, which forms the
recipient address for the message, e.g.,
That is, the local-part of the remote printer server's address is
ALWAYS "remote-printer", and the domain-part is constructed by
reversing the telephone number, converting each digit to a domain-
label, and being placed under "tpc.int."
The message is routed in exactly the same fashion as all other
electronic mail, i.e., using the MX algorithm [3]. Since a remote
printer server might be able to access many printers, the wildcarding
facilities of the DNS [4,5] are used accordingly. For example, if a
remote printer server residing at "dbc.mtview.ca.us" was willing to
access any printer with a telephone number prefix of
+1 415 968
then this resource record might be present
*.8.6.9.5.1.4.1.tpc.int. IN MX 10 dbc.mtview.ca.us.
