pszLogAddress (PSZ)
This is required for an OD_DIRECT device being opened with DevOpenDC; it is the logical device address, such as "LPT1" on OS/2. Some drivers may accept a file name for this parameter or even a named pipe.
Where output is to be queued (for an OD_QUEUED device), this is the name of the queue for the output device. The queue name can be a UNC name.
Note: This parameter can be a port name for a printer device context.
