Comparing NDPS with Queue-Based Print Services

Queue-Based (Legacy) Print Services
Administrators create and link print queues,
printers, and print servers, and users submit print
jobs to the queues. These three objects must be
maintained separately once the system is in place.
Uni-directional communications only. Feedback
consists of pop-up windows reporting a
nonconfigurable set of events.
The architecture of Novell legacy queue-based print services was based on the
creation and linking of three components: printers, print queues, and print
servers. Setting up queue-based printing was often a complex task. In order to
print, users first had to capture the printer port. Then the client would redirect
the data to a file in a print queue, where it was stored while waiting to be sent
to a printer by the print server.
With NDPS, printer, print queue, and print server functions are combined into
a single entity called a Printer Agent. The need to create print queues has been
eliminated, and users send print jobs directly to printers.
Even though NDPS does not require queues, your networks might continue to
include queue-based printers and clients not currently supported by NDPS.
The backward compatibility of NDPS allows you to continue using these
queue-based services and resources transparently, as is illustrated in the
following scenarios:
You can print through NDPS to an existing queue, allowing you to access
systems that require a queue connection (for example, mainframe systems
using NetWare HostPrint
NDPS can service existing queues, allowing you to use NDPS on the
server even though your client platform is not currently running NDPS.
This allows you to install and run NDPS while you are changing your
client workstations to NDPS.

Novell Distributed Print Services
Administrators create Printer Agents, allowing
users to submit print jobs directly to printers. All
management functions are centered on the printer
itself.
Bi-directional communications supported.
Configurable event notification includes e-mail,
pop-up windows, event logs and other methods,
including third-party methods such as beepers and
faxes. Events reported are limited only by a printer's
capability.
