printer redirection ,impl MS-RDPEXPS protocol

When using the mstsc client to remotely connect to an MS host, if the remote host does not have a printer driver corresponding to the client, the remote host will map the printer through Remote Desktop Easy Print. However, the wfreerdp client does not have this function. Upon investigation, it was found that freerdp has not implemented the MS-RDPEXPS protocol. How can I implement it? Are there any reference examples? Because I sent specific instructions based on this protocol, but the server did not reply to me, I cannot determine whether the data I sent was correct
