Understanding the Service Registry Service
The Service Registry allows public access printers to advertise themselves so
that administrators and users can find them. This service maintains
information about device type, device name, device address, and device-
specific information such as the printer manufacturer and model number.
Before Novell Distributed Print Services (NDPS), each printer had to
periodically advertise its availability through the Service Advertising Protocol
(SAP), which was effective but created a lot of traffic on the wire.
The Service Registry Service helps minimize the network traffic problem
created by many printers advertising through the SAP. (For information on
turning off the SAP, see the documentation for your printer.) When you attach
a public access printer to the network, it registers with the SRS. When an
application or user wants to use a printer, it can contact an SRS and retrieve a
list of all registered printers on the network.
