This sample demonstrates how to implement AsyncNotification to communicate between registered applications and printing components loaded in the spooler. The client part of the sample is a simple application that registers for Async print notifications and acts as the listener. The server part of the sample opens a notification channel and acts as the sender. The server part of the sample is compiled as a library to be linked to a port monitor or a print processor.
