This chapter is concerned with conversion – the one from legacy print protocols such as port 9100, WS-Print, and LPR to IPPS. While every network or enterprise can benefit by adopting IPP/IPPS as their print protocol, for Windows-based components the incentive to convert is particularly high. Assuming you have convinced management to make the wise leap from legacy print protocols, you will need a way to ensure the change is as seamless a transition as possible. While not a complex task, you will need to do sufficient planning to ensure all bases of print services are covered. For instance, while client-server print transition should be straightforward to plan, have you ensured that mainframe or midrange print services were considered? Have you ensured that no enterprise application or script will be affected by the transition? Have you planned to remove legacy print protocol services from network printers? Have you planned to remove legacy print drivers from the client and server machines in the network, and if so, how will this be done? As expected, planning the conversion is essential to the project's eventual success. Obviously, there is not a singular method that would cover all networks, but there are key points that need to be addressed in any enterprise.
