LaserWriters 12/640 and 16/600: Ports Listen To and Used.

Customer wants to know the ports other than 515 that the LW 12/640 and 16/600 listen to and use.

Customer has an application (Easy Spooler) running on AIX 4.1.4 that requires two ports. She is sending page formatting commands via PCL to control the printer but it times out and resets after each page rather than at the end of the job.

LPR works great, Appletalk printing works great, printer ROM level is 1.0.

She says the Easy Spooler requires a port above 1023.
Apple LaserWriters use port (socket) 515, which is the default number specified by RFC 1179. Port 515 should be used for all printing jobs. If Easy spooler requires a port above 1023 there will be an ongoing conflict.

This feature is not part of RFC 1179 and is not part of the LPR printing standard, the standard we implemented and support.

Alternative:
Use LPR and port 515, or use a device that accepts LPR jobs using TCP/IP and forward them as PAP jobs using AppleTalk.
