This was a desktop publishing word processor, positioned as a high-level top-end machine and marketed by Toshiba in 1990. The DTP-7000 was equipped with the Japanese language word processing features previously developed by Toshiba, while providing the special high-level printing capabilities required for desktop publishing, such as sophisticated page composition, creation of complex layouts, linkage with phototypesetters, and connection with various printers.
The DTP-7000 provided support for a wide range of Japanese language word processing capabilities, including a kana-kanji conversion function for entire sentences, a document brush-up feature based on AI technology (previously used in business word processors), synonym conversion using a synonym dictionary, and an intelligent layout feature for automatically determining layout by understanding sentence structure.
DTP requires connection of special equipment (printers and image scanners etc.), and customization is necessary for incorporation into a large system. An open architecture was used to meet these needs for DTP. For example, it used UNIX System V, X-Windows, NFS, PostScript interfeces, and interfaces for RS-232C, Centronix and SCSI. (However, the system was designed to start up by just switching on power during use as an ordinary word processor, and this eliminated the mismatch with conventional word processor operation).
