A signaling method for asynchronous, fully interlocked, bidirectional parallel communi-cations between hosts and printers or other peripherals is defined. A functional subset of thesignaling method may be implemented on personal computers (PCs) or equivalent parallel porthardware with new software. New electrical interfaces, cabling, and interface hardware thatprovides improved performance while retaining backward compatibility with this subset is detailed.

IEEE Standard for Interface and Protocol Extensions to IEEE Std 1284 Compliant Peripherals and Host Adapters
Administratively Withdrawn February 2006 System extensions consistent with the implementation and functionality of IEEE Std 1284-2000 are covered. Multiport expansion architectures, daisy chains, an application and devicedriver programming interface architecture, and data link layer services are explored.
IEEE Standard for Data Delivery and Logical Channels for IEEE Std 1284 Interfaces
Administratively Withdrawn February 2006 A device to carry on multiple, concurrent exchanges of data and/or control informationwith another device across a single point-to-point link allowed by the packet protocol is describedin this standard. The protocol is not a device control language. The protocol provides basictransport-level flow control and multiplexing services. The multiplexed information exchanges areindependent, and blocking of one has no effect on any other. The protocol shall operate over inter-faces such as described in IEEE Std 1284-2000.
IEEE Standard for Information Technology -Transport Independent Printer/System Interface (TIP/SI)
A protocol and methodology for software developers, computer vendors, and printer manufacturers to facilitate the orderly exchange of information between printers and host computers are defined in this standard. A minimum set of functions that permit meaningful data exchange is provided. Thus a foundation is established upon which compatible applications, computers, and printers can be developed, without compromising an individual organization's desire for design innovation.
