CHAPTER 5: Protocol Overview

The EPS provides two major methods of printing via TCP/IP. Berkeley Remote LPR is supported, as is the RTEL software. Both methods provide queueing of jobs on the host if the host is busy with another job. The remote LPR software allows the EPS to look like another host that can spool and print files, and hosts wishing to print to the EPS simply send the print data and assume the EPS will handle it properly. The RTEL software, which you must install and configure on the host, provides more functionality than remote- LPR. It allows the host’s lp or lpr printing system to transparently use the EPS’s print devices, and also allows you to create tty devices on the host that map to the EPS.

The EPS’s IP address must be set before you can use any of the TCP/IP functionality. You can set the address by hand or via BOOTP or RARP— see Chapter 3 for more details. In general, you must tell the EPS’s address to any host wishing to access the EPS. You can usually configure this via a file (/etc/hosts) containing all the local IP addresses, or a nameserver on the network. Specifying a gateway IP address on the EPS allows the server to reply correctly to non-local network connections.

TCP/IP print services are entirely host driven—the EPS does nothing until a host connects to it and requests a print job. The service does not check to see if the EPS and the print resource exists on the host until you queue a print job. The only time the EPS will initiate a connection is to tell a host to start a previously queued job.

5.3 AppleTalk

AppleTalk includes a variety of network media types. LocalTalk is frequently used to refer to AppleTalk running over 230 kbps serial lines. All Macintosh computers provide LocalTalk support, but the EPS does not. The other two types, EtherTalk and TokenTalk, provide AppleTalk over Ethernet and Token Ring, respectively. The EPS supports only EtherTalk, so most Macintosh computers will need either an Ethernet card or a LocalTalk-to-EtherTalk router to connect to the EPS’s services. TokenTalk users wishing to use the EPS print services have to have an Ethernet-Token Ring bridge or router to connect the two networks. In the following discussions, AppleTalk refers only to EtherTalk.

The EPS provides only enough of the AppleTalk protocol stack to provide printing. You can only access the EPS as a LaserWriter from an AppleTalk client (Chooser menu, etc.) The device name that shows up in the Chooser menu is the name of the service defined on the EPS. If the EPS service name is “LAB_SERIAL,” that’s what will show up in the client Macintosh computer’s Chooser menus.
