2 Instance of Print Library based on gEfiPrint2SProtocolGuid.\r
3\r
4 Implement the print library instance by wrap the interface \r
5 provided in the Print2S protocol. This protocol is defined as the internal\r
6 protocol related to this implementation, not in the public spec. So, this \r
7 library instance is only for this code base.\r
