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.

If you want to provide customized postprocessing of the scan line data stream before it is spooled, you can do so by implementing the IPrintOemUni::FilterGraphics method in a rendering plug-in. There are no GPD file entries associated with this Unidrv feature.
