“With the release of Windows 10 21H2, Windows offers inbox support for Mopria compliant printer devices over network and USB interfaces via the Microsoft IPP Class Driver. This removes the need for print device manufacturers to provide their own installers, drivers, utilities, and so on. Device experience customization is now available via the Print Support Apps that are distributed and automatically installed via the Windows Store,” the company wrote.
AFAIK, Mopria doesn’t develop universal printing standards actually. The IPP standard was developed by Printer Working Group of IEEE. Of course, its members are almost same as Mopria. The standard Mopria developed is eSCL, a scanning standard. eSCL has a competitor, WSD, which was developed by Microsoft.
