| EPP
Developed by Intel, Xircom, Zenith, and other companies, the EPP spec
builds on the design of the humble parallel port, adding two-way
communications and faster exchange. It's been used in laptops since
mid-1991, where it has been in great demand because of the proliferation
of hard disks, tape backup units, CD-ROM drives, and other mass-storage
devices that use parallel ports. Since both EPP and ECP are supported by
the IEEE 1284 specification, many new parallel ports can run in either
fashion. |
