In this chapter, we will explore some great software development and learning aids you might employ to gain a better understanding of IPP/IPPS. By now, you are well versed with Wireshark, likely the best diagnostic tool for IPP you can use. The tools in this chapter take it up a notch and create or accept stricter enforcement of the IPP RFC standards. For instance, if you develop against a hardware vendor whose enforcement of IPP is a bit loose, you might find that your code will not work on another vendor’s print hardware. If you are a print hardware manufacturer, you might want to develop an IPP/IPPS network services stack or server-side implementation of IPP. In short, engineers might want to
