LaserWriter Printers: TCP Maximum Segment Size

Apple LaserWriter printers determine their TCP MSS by the IP address of sender, the printer's IP address, and the printer's subnet mask.

Here is a chart of the behavior:

Model	Local	Non-Local
LaserWriter 8500	1460	536
LaserWriter 12/640 PS	1460	536
LaserWriter 16/600 PS	1460	536
Color LaserWriter 12/600 PS	1460	1460
Color LaserWriter 12/660 PS	1460	1460
Table Notes 1. Local = host and printer are on same network and subnet. 2. Non-Local = host and printer are on different networks or subnets.

These are the MSS values sent from the printer to the host. The actual MSS used in a particular print job may vary depending on the network topology and the behavior of the host.
