Abstract

This document is one of a set of documents, which together describe all aspects of a new Internet Printing Protocol (IPP). One of the purposes of this document is to compare the functionality of the two protocols. Another purpose is to facilitate implementation of gateways between LPD and IPP. This memo defines an Experimental Protocol for the Internet community.

IESG Note

This document defines an Experimental protocol for the Internet community. The IESG expects that a revised version of this protocol will be published as Proposed Standard protocol. The Proposed Standard, when published, is expected to change from the protocol defined in this memo. In particular, it is expected that the standards-track version of the protocol will incorporate strong authentication and privacy features, and that an "ipp:" URL type will be defined which supports those security measures. Other changes to the protocol are also possible. Implementors are warned that future versions of this protocol may not interoperate with the version of IPP defined in this document, or if they do interoperate, that some protocol features may not be available.

The IESG encourages experimentation with this protocol, especially in combination with Transport Layer Security (TLS) [RFC 2246], to help determine how TLS may effectively be used as a security layer for IPP.

RFC 2569 Mapping between LPD and IPP Protocols April 1999

Abstract

This document is one of a set of documents, which together describe all aspects of a new Internet Printing Protocol (IPP). IPP is an application level protocol that can be used for distributed printing using Internet tools and technologies. This document gives some advice to implementers of gateways between IPP and LPD (Line Printer Daemon). This document describes the mapping between (1) the commands and operands of the ’Line Printer Daemon (LPD) Protocol’ specified in RFC 1179 and (2) the operations, operation attributes and job template attributes of the Internet Printing Protocol/1.0 (IPP). One of the purposes of this document is to compare the functionality of the two protocols. Another purpose is to facilitate implementation of gateways between LPD and IPP.

WARNING: RFC 1179 was not on the IETF standards track. While RFC 1179 was intended to record existing practice, it fell short in some areas. However, this specification maps between (1) the actual current practice of RFC 1179 and (2) IPP. This document does not attempt to map the numerous divergent extensions to the LPD protocol that have been made by many implementers.
