"How can I send something?"

Other Languages: English

What's the simplest way?

You should read the Fax By E-mail instructions... In short, you address your message as follows:

    To: remote-printer.Arlington_Hewes/Room_403@14159682510.iddd.tpc.int

or

    To: remote-printer.Arlington_Hewes/Room_403@0.1.5.2.8.6.9.5.1.4.1.tpc.int

This will get automatically routed to a remote printer server, which will transmit a facsimile to the recipient. When the transmission completes (or fails), an email message will be sent back to you.

Fine. What does this mean? (Left hand part)

Let's look at the text on either side of the '@'-sign.

The left-hand part identifies the kind of access (remote-printer) along with the identity of the recipient (Arlington_Hewes/Room_403).

Because some mailers have difficulty dealing with addresses that contain spaces, etc., you should be very careful as to what characters you use to identify the recipient. It safest to use upper and lower case letters, digits, and two special characters ('_' and '/').

When a cover sheet is generated, the '_' will turn into a space and the '/' will turn into an end-of-line sequence. So, given the address above, the cover sheet might start with

Please deliver this facsimile to:
Arlington Hewes
Room 403

The information is formatted on the coverpage along with a bit about TPC.INT and a banner from the fax server cell. Coverpage details are listed along with some samples in the Coverpage FAQ.

What about the rest of it? (Right hand part)

The right-hand part identifies the telephone number of the remote-printer. It must be an international telephone number. Telephone numbers are usually written like this:

    +code-number

where "code" identifies the country and "number" is the telephone number within the country, e.g.

    +1-415 968 2510

In the above example, the USA country code +1 is given, then an area code for California (SanFrancisco) which is 415. the remainder is the phone number. For those interested in telephonic trivia, the maximum number of digits is 15. In order to get the Internet e-mail infrastructure to automatically route messages, the punctuation characters are stripped out, e.g.,

    14159682510

and then the string is inverted and turned into an Internet domain name, e.g.,

    0.1.5.2.8.6.9.5.1.4.1.tpc.int

Note that the telephone number should not include any international access codes. Here's why: if, from the US, I wanted to call someone in Tokyo (+81-33-...), I would dial something starting with "0118133" The first three digits (011) is the international access code for the US. If I were to call that same number from FR, I would dial something starting with "198133". The first two digits (19) is the international access code for FR. In contrast, the tail of the domain name for Tokyo is always

    3.3.1.8.tpc.int

regardless of where in the world you are sending your mail. This approach allows us to map from the Internet naming scheme onto the entire international telephone network. And, as you might expect, you can mix remote-printing and e-mail recipients in the same message, e.g.,

To: remote-printer.Arlington_Hewes/Room_403@0.1.5.2.8.6.9.5.1.4.1.tpc.int
cc: mrose@dbc.mtview.ca.us (Marshall Rose)

In fact, the replies generated by the e-mail recipients can even go to the remote-printing recipients.

Another example (United Kingdom)

The example above uses a fax number in the United States. Sending a fax to other countries works the same way, except the international country code is different. The following example uses a UK fax number along with the UK iddd code of +44.

    To: remote-printer.Arlington_Hewes/Room_403@441813434622.iddd.tpc.int

or

    To: remote-printer.Arlington_Hewes/Room_403@2.2.6.4.3.4.3.1.8.1.4.4.tpc.int

Note the placement of the iddd code of 44 to indicate the fax number is in the UK. Other countries have their own iddd numbers. (Germany=49, etc) Consult the iddd list for further assistance.

Suppose I want to send images instead of text?

Use MIME

MIME is the Internet-standards track technology for multi-media messaging. Remote printer servers support, at a minimum, the following MIME content types:

So, you might send something like the following:

To: remote-printer.Arlington_Hewes/Room_403@0.1.5.2.8.6.9.5.1.4.1.tpc.int
MIME-Version: 1.0
Content-Type: application/postscript
%!
...

Is there software to help me compose messages like this?

Yes. See the web page on Client Software for TPC
