    abstract =  {This document defines a schema, object classes and attributes, for printers and printer services, for use with directories that support Lightweight Directory Access Protocol (RFC 4510). This document is based on the printer attributes listed in Appendix E of Internet Printing Protocol/1.1 (IPP) (RFC 2911). A few additional printer attributes are based on definitions in the Printer MIB (RFC 1759), IEEE-ISTO PWG Command Set for IEEE 1284 Device ID (PWG 5107.2), or IEEE-ISTO PWG IPP Job and Printer Extensions - Set 3 (IPP JPS3).},
