DISCUSSION

    You use the Apple LocalTalk Bridge to share LocalTalk-only devices, such as some LaserWriter printers, PowerBook computers, or Newton MessagePad communications devices, on an Ethernet or Token Ring network. With the LocalTalk Bridge, you can access an Ethernet or Token Ring network while maintaining a seamless connection to your LocalTalk network. The LocalTalk Bridge is a commercial product, Apple part number M3246Z/A.

    You use the Apple LaserWriter Bridge much as the LocalTalk Bridge, except the LaserWriter Bridge is for printers only. You can share any printer that uses the LaserWriter icon in the Chooser using the LaserWriter Bridge. The LaserWriter Bridge is available for download at Apple Software Update sites on the Internet and many online services.

    To use either of these utilities with Open Transport, you need to use version 2.1 or later of the utilities. This package includes a program to update LocalTalk Bridge 2.0 or 2.01 software to version 2.1. It also includes version 2.1 of the LaserWriter Bridge program.
