Implementing Printer Driver COM Interfaces

Important

The modern print platform is Windows' preferred means of communicating with printers. We recommend that you use Microsoft's IPP inbox class driver, along with Print Support Apps (PSA), to customize the print experience in Windows 10 and 11 for printer device development.

For more information, see Modern print platform and the Print support app design guide.

This section explains how to construct a plug-in, based on WDK-supplied sample code. It also explains the calling sequences used for communication between the printer drivers and plug-ins. This section includes the following topics:
