ervices) A printing protocol co-developed by Novell, Xerox and HP that provided print services on NetWare file servers. It first shipped as an option for NetWare 4 in 1997. NDPS supported bi-directional capability with sophisticated features such as emailing the toner supplier before the toner ran out. The successor to Novell's Queue Management Services (QMS) printing protocol (see QMS
), NDPS relied on NetWare's bindery or NDS directories to identify printer resources.
Based on SNMP and ISO 10175 open standards, NDPS ran as an NLM on a NetWare server, and the client ran under Windows. It supported QMS and LPR/LPD plus third-party gateways to other printers. Starting with NetWare 5, NDPS added JetDirect and Xerox protocols. See NLM
