Building OEM Printer Customization Plug-in Samples

In readme, at point 2, it says add non-binary files to Package project. But there is no package. Package is inside xpsdrvsmpl example. How should I proceed? Thanks.

The package project is inside the Package folder, in package.VcxProj.

But they are at different folders (OEM Printer Customization Plug-in Samples vs XPSDrvSmpl). Did you suggest something else?

These plugins are not installed by themselves, they are installed as part of another print driver. Do you already have a print driver?

No, I do not. Actually I was trying to get the filename or the file content before printing. Will forward content/filename to dlp(data loss preventation) product. Someone suggested UI plugin in this thread. What do you suggest?
