/** @file
Module produces EDK gEfiPrintProtocolGuid for backward compatibility support.
EDK II retires old EDK Print Protocol and this module produces
gEfiPrintProtocolGuid based on PrintLib:
1) If it links against BasePrintLib in MdePkg, it produces gEfiPrintProtocolGuid
without any prerequisites.
2) If it links against DxePrintLibPrint2Protocol in MdeModulePkg, it produces
gEfiPrintProtocolGuid on top of gEfiPrint2ProtocolGuid.
