This article describes configuring TCP/IP communications to a LaserWriter Pro 16/600 PS.
DISCUSSION
To Find the IP Address and Other TCP/IP Configuration Information The IP Address To find the IP address use one of the choices below: Subnet and Default Gateway Displayed To find the subnet and default gateway use one of the choices below: RARP and BOOTP On startup, if the IP address is set to 0.0.0.0 (or has never been set), the LaserWriter 16/600 PS will issue BOOTP and RARP requests roughly every 5 seconds. If your printer has ROM version 1.0, these requests seem to be continuous, while ROM version 2.0.x these requests seem to stop after 64 seconds, or 12 broadcasts. Verifying the IP Address when using RARP or BOOTP The Apple Printer Utility will correctly display the current IP address. Network management software may also display the current IP address. Since the "permanent" address is still 0.0.0.0, printing a test page by restarting the printer will not display the served IP address. The test page will still report, "IP address: 0.0.0.0". Configuration Switch and RARP or BOOTP Does the configuration switch on the printer affect RARP and BOOTP? No, RARP or BOOTP work if the switch is set in up or down position. How do I Manually Assign the IP Address If the "permanent" address at 0.0.0.0 can I use gleaning? If the IP address has been set permanently, how do I change it? You can use one of the following: TELNET and use option x apple printer utility NOTE : RARP, BOOTP and IP gleaning do not work here. Turning IP Off There is no way to completely turn off all IP functions on the printer. However, customers who ask, "How do I turn IP off," are actually asking for two different configurations.
2. Keep IP hosts from printing to the printer -- If you want to hide your printer from the TCP/IP network, and not let other hosts print to the printer, assign an IP address to the printer that is not in use. This will cut off all printing from outside the subnet. Local LPR clients will still be able to use the printer. Support Issues Acquires Wrong Address Because the printer is using a BOOTP or RARP server, the printer is in glean mode when the address is 0.0.0.0, some users may see this issue. Subnets with heavy ARP traffic or malfunctioning systems may accidentally configure the printer. The printer may accept the wrong configuration method. For example, the network administrator wanted the printer configured with RARP, but a BOOTP server responded more quickly. A user's printer unintentionally "steals" a number from a BOOTP server. BOOTP Client Using Another Client's BOOT Address The LaserWriter 16/600 previously accepted BOOTP (and DHCP) response packets intended for a different host and would assume that host¹s IP address. This was resolved by version 3.0 ROMs. BOOTREQUEST Packet Is Interpreted as DHCPDISCOVER by a DHCP Server This may be an issue with the BOOTREQUEST sent by the printer. The most likely cause is the DHCP server does not properly conform to RFC 1534. If you do a network trace, check for DHCP option 53 (message type). If the printer's BOOTREQUSET uses option 53, then the printer is out of specification. |
