"Thanks for visiting TPCint.org. While performing a WHOIS look up, I only identified one person remaining at TPC.int, so I decided to keep the spirit of TPC.int alive by creating this informational site."
TPC.int began the idea of Remote Printing back in 1993. Document number RFC1530 states, "The primary purpose of the tpc.int subdomain is to provide transparent mappings between users of general-purpose computers on the Internet and special-purpose devices directly connected to the telephone network."
The Internet Multicasting Service, TPC.int, is a non-profit organization that operates a free e-mail-to-fax service. They rely on volunteers from the U.S., Australia, Canada, Denmark, Germany, Greece, Hong Kong, South Korea, New Zealand, Portugal, Sweden, Taiwan, and the United Kingdom, who maintain fax servers in their particular areas, so all phone calls to fax machines are local.
To send a fax using TPC.int to someone, first create the e-mail message. Then use the following address, replacing the italicized variables with the actual person's name and phone number, but keeping the punctuation (including the underline) intact:
remote-printer.First_Last@13135551234.iddd.tpc.int
Note that the phone number is one continuous string of numbers, and it must include the 1 and the area code, even if the fax is just being sent across town. The service automatically sends you an e-mail confirmation either stating that the fax transmission was successful or did not go through because there is no local fax server in that area.
