The last chapter provided a high-level overview of one of the central tenets of IPP: the Get-Printer-Attributes request. Because that chapter provided code created with WinRT APIs, the lower-level workings of the protocol were abstracted away. In this chapter, we take a deeper dive into the Get-Printer-Attributes request and, more specifically, the protocol workings in general. Looking into the lower-level workings is not for everyone; however, if you genuinely want to understand how IPP works and how to troubleshoot issues that arise, I encourage you to at least give this chapter a once-over.
