The Remote Printer protocol (RP) is inherently IPX-based. Configurations
using printers in remote printer mode can use one of the following
configurations to conform to an IP setting:
As stated before, the best way today to communicate to a printer with NDPS
is through a third-party gateway. If you plan to reconfigure a printer to support
IP, you should check whether a third-party gateway for that printer has become
available.
Option #2 is simpler and offers better performance than option #3, but it
requires the printer to support LPR/LPD mode and have IP configured.
Options #4 and #5 are also simple, but they might not be a viable option in
some settings because they require the printer to be directly attached to a
workstation or server. Of the three options, only #5 maintains a Pure IP
environment.
Option #3 requires an isolated IPX segment to exist in the network.
Communication with this segment can be filtered and/or translated by a
Migration Agent, thus maintaining the IP segments free of IPX
communication. The advantages of option #3 are that it doesn't require any
changes to the current printing configuration and doesn't add much overhead
to networks that already manage isolated IPX segments.
