reception fichiers *.dwg

Est-il possible de recevoir des fichiers *.dwg, et quels sont les fichiers que mail print ne peut recevoir

Mail Print doesn't have any internal support for .dwg files.

If an application is registered for drag and drop printing it will attempt to use that. You can check this in Windows, if you try and drop a .dwg file on a printer in Windows and it prints then Mail Print should work with it. If you can't drop it then it won't work.
