2 Module produces EDK gEfiPrintProtocolGuid for backward compatibility support.
3
4 EDK II retires old EDK Print Protocol and this module produces
5 gEfiPrintProtocolGuid based on PrintLib:
6 1) If it links against BasePrintLib in MdePkg, it produces gEfiPrintProtocolGuid
7 without any prerequisites.
8 2) If it links against DxePrintLibPrint2Protocol in MdeModulePkg, it produces
9 gEfiPrintProtocolGuid on top of gEfiPrint2ProtocolGuid.
