2.2.4.2.3 Server Convert Devmode Request (CONVERT_DEVMODE_REQ)
When the server operating system installs the virtual printer driver, it calls into it to convert an internal DEVMODE structure into a printer-specific DEVMODE structure. This message redirects this call to be processed by the client-side printer driver.
