5 EtherTalk environment

EtherTalk is AppleTalk used in an Ethernet network. This protocol is widely used in Macintosh network environments. Microsoft Windows system also supports this protocol. Like TCP/IP, EtherTalk also provides packet transmission and routing functionality.

The network printer card works on EtherTalk networks, if the host printer supports PostScript. The description in this chapter applies to network printing from a Macintosh computer.

EtherTalk printing

Printing in an EtherTalk network is possible with several different hardware and software configurations. When you issue a command to print a document, the application begins a series of EtherTalk calls attempting to establish a connection to the printer. The calls first initiate the NBP (Name Binding Protocol) name-lookup process to find the currently selected printer and its EtherTalk address. Then the Printer Access Protocol (PAP) is used to open a connection with the printer.

Once the connection has been established, the workstation and printer interact over a PAP connection. PAP uses lower-level protocols, such as ATP and DDP, to provide a data-stream service for sending print data to the printer.

Configuring EtherTalk

You can configure EtherTalk using the following method:

Web Image Monitor SP 3300 Series

1Run your web browser.

2Enter the printer's IP address in the URL field and click Go.

3Select Network Settings > EtherTalk.

•EtherTalk Protocol: allows you to enable or disable the EtherTalk protocol.

•Printer Name: allows you to set the printer name for EtherTalk protocol. The default name is RNP+MAC address. This name is automatically displayed on Chooser.

•Printer Type: shows the printer type.

• Last Error Occurred: shows the last error.

•RTMP (timer value for aging A-Router entity): allows you to set the time in seconds after which the routing table entry maintained by the RTMP protocol times out.

•PAP (wait time before transmitting a tickle packet): enables you to define the time interval in seconds after which the PAP protocol should resend a tickle packet to verify the status of the PAP connection between the printer and your Macintosh.

•ZIP (current zone): shows the AppleTalk Zone name. If there is no configured zone, *(asterisk) should be displayed.

4Click Apply.

Configuring the printer

Note: The following instructions are for Mac OS 10.3, but similar for other versions.

The following steps must be taken to configure the network printer for use on a Macintosh system. If the network printer you want to use is not listed in the printer pop-up menu when you try to print a document, you should add it to your list of available printers.

1Open the Applications folder > Utilities, and Print Setup Utility.

•For MAC OS 10.5, open System Preferences from the Applications folder, and click Printer & Fax.

2Click Printing > Set Up Printers.

3If the printer already appears in the printer list, select the In Menu check box to add it to your list of available printers. You will see the printer in the Printer pop-up menu the next time you print.

4Click Add on the Printer List.

•For MAC OS 10.5, press the “+” icon then a display window will pop up.

5For MAC OS 10.3, select the Rendezvous tab.

•For MAC OS 10.4, click Default Browser and find the Bonjour.

•For MAC OS 10.5, click Default and find the Bonjour.

6If necessary, choose an AppleTalk zone from the pop-up menu that appears directly below it. Any AppleTalk printers in the zone you have chosen appear in the Printer List.

7Select the printer in the Printer List.

8To use printer-specific features, choose the item appropriate for your printer from the Printer Model pop-up menu, then select your printer in the Model Name list.

9Click Add.

The printer appears in the Printer List as the default printer (in boldface). It also appears in the Printer pop-up menu when you print a document.
