A recently discovered bug in the Domain/OS sio driver is the
cause of your problem. What is happening is that lpd reopens the
sio port for each new job. The open process flushes the output buffer
and sio state, thus deleteing any output waiting to be sent from the
previous job. Also lost is the state information, which may include
the xoff/xon state. The fix will be to wait until the output buffer
is empty before closing the connection.
Sorry, but I can't give you a date as to when this fix will be implemented.
I sugest you file an apr so you will be notified of the fix. Include
the text of this message to speed processing of the apr.
