Migrating From Ipx-Based Ndps To Ip-Based Ndps - Novell NETWARE 6-DOCUMENTATION Manual

Migrating from IPX-Based NDPS to IP-based NDPS

Novell Distributed Print Services Administration Guide
The first NDPS configuration above is not recommended because a back-end
queue is still required, increasing network traffic and delaying job completion.
In addition, while transitioning to NDPS, there would be two queues in the
print path as shown in the following illustration:
NDPS Manager
PA
Printer
Novell

If you are migrating a QServer-mode printer, we recommend that you
reconfigure it for LPR as in configuration #5 or RP as in configuration #2 if
possible. Choose configuration #5 if the network supports IP and the printer
supports LPR/LPD. Choose configuration #2 if the network supports IPX and
the printer supports RP. Configurations #3 and #4 are available if the printer
does not support LPR or RP, but you still want to benefit from many NDPS
features without the need for a queue. Notice that configurations #2 through
#5 require you to configure the print device to enable a new protocol.
Notice that if the NPRINTER.EXE in configuration #3 is running on a
NetWare client, it is possible to realize IP-only printing to a remote printer,
though not Pure IP. However, if IP is desired, configuration #5 is preferable
and is Pure IP.
IPX NDPS
NDPS 3.0, which is included in NetWare 6, is written to support IP natively.
All communication between NDPS clients and NDPS back-end services will
automatically switch to use the protocol or protocols available at the client and
server. Thus, much of the effort to switch to an IP network will consist of
configuring the clients and servers to use IP only. (This is normally done
during the installation process.) However, there are some protocols used by
