Types of server communication

Now that we understand how pdservers work together, we can talk about the two types of server communications. InfoPrint Manager clients always communicate with the command processor part of the pdserver, and this is called client to server communication. When any of the three parts of the pdserver communicate with any other part of a pdserver this is called server to server communication.

For clients to work with a pdserver, they need:

1. A way to locate a pdserver
2. A way to communicate with a pdserver

For pdservers to work together, whether they are on the same machine or different machines, they need:

1. A way to locate each other
2. A way to communicate with each other
