ETHERNET PRINT SERVER

An AppleTalk zone name is configurable, in case there are multiple zones on the LAN to which the EPS is connected. If you are using the default zone or only one zone, you do not need to configure any information on the EPS. Only AppleTalk routers provide zones, so if you have no router on your network, you will not need a zone configuration.

Many third-party packages are available that provide AppleTalk support on UNIX or other operating systems. You can use these to print to the EPS via AppleTalk, but it is typically more efficient and easier to configure printing via the native UNIX or TCP/IP print utilities (lp or lpr).

Like TCP/IP, AppleTalk is passive regarding printing jobs. When a client wishes to print, it will send out a broadcast asking what print resources are available. The EPS will answer, and the client will request a print job to the EPS. If the print resource is available, the print job will complete normally. If the print resource is busy, however, the EPS will enter a prolonged “arbitration” phase to keep track of which print client has been waiting for the resource the longest. In this phase, multiple clients may be sending packets to the EPS once every 2-5 seconds until the resource is available and their jobs are serviced.

The parallel port service does not have AppleTalk enabled. AppleTalk printing typically requires a bi-directional data path, so the printing node must be able to receive data from the printer port as well as send to it. Since the parallel port on the EPS is not bi-directional, AppleTalk clients will not be able to print to it. This is not a PostScript or printer limitation, but an AppleTalk limitation. You can use any PostScript printer with the parallel port if the host does not need information returned from the printer.

5.4 LAT

Like AppleTalk, LAT was designed to let nodes on a LAN quickly and easily access other nodes’ resources. There is, however, little support for raw data streams, file services, or other operating-system related items. LAT is more intended for host connections to limited-function nodes (printers, terminal servers, etc.). Central to LAT is the concept of “services,” or resources that another LAT node can use. Services on the EPS can be associated with one or both physical ports, and each port can be associated with multiple services. LAT nodes typically send out announcements (“multicasts”) telling what resources they provide. Other LAT nodes listen to these periodic announcements, and will connect to the node to use these services whenever requested.
