Supported network protocols The HP Color LaserJet 2820/2830/2840 all-in-one supports the TCP/IP network protocol. It is the most widely used and accepted networking protocol. Many networking services utilize this protocol. The following table lists the networking services/protocols that are supported on the HP Color LaserJet 2820/2830/2840 all-in-one. The following operating systems support network printing: ● Windows 98 SE ● Windows Me ● Windows 2000 ● Windows XP ● Macintosh OS X v10.
IP addressing ENWW Service name Description DHCP (Dynamic Host Configuration Protocol) For Automatic IP address assignment. DHCP server provides device with IP address. Generally requires no user intervention for printer to obtain IP address from a DHCP server. BOOTP (Bootstrap Protocol) For Automatic IP address assignment. BOOTP server provides device with IP address.
TCP/IP configuration To operate properly on a TCP/IP network, the printer must be configured with valid TCP/IP network configuration parameters, such as an IP address that is valid for your network. CAUTION Changes to these settings might result in a loss of functionality with your device. For example, network scanning, network faxing, or HP Web JetAdmin might stop working with certain settings changes.
TCP/IP configuration tools Depending on your printer and operating system, the printer can be configured with valid TCP/IP parameters for your network in the following ways: NOTE ENWW ● Using Software—You can use the HP Toolbox software, or you can use the device Embedded Web server by entering the IP address in your Web browser. ● BOOTP—You can download the data from a network-based server using BOOTP (Bootstrap Protocol) each time the printer is turned on.
Using BOOTP BOOTP (Bootstrap Protocol) provides a convenient way to automatically configure the printer for TCP/IP network operation. When powered on, printer sends a BOOTP request message onto the network. A properly configured BOOTP server on the network will respond with a message that contains basic network configuration data for printer. The BOOTP server’s response may also identify a file that contains extended configuration data for the print server.
Configuring the BOOTP server For the printer to obtain its configuration data over the network, the BOOTP server must be set up with the appropriate configuration files. BOOTP is used by the printer to obtain configuration data located in the /etc/bootptab file on a BOOTP server. When the printer is powered on, it broadcasts a BOOTP request that contains its MAC (hardware) address.
Tags supported in a BOOTP/DHCP boot file (continued) NOTE 14 Option Description vm The BOOTP report format tag (required). Set this parameter to rfc1048. ha The hardware address tag. The hardware (MAC) address is the link-level, or station address of the printer. It can be found on the printer network configuration page as the HARDWARE ADDRESS. ip The IP address tag (required). This address will be the printer's IP address. sm The subnet mask tag.
Using DHCP Dynamic Host Configuration Protocol (DHCP, RFC 2131/2132) is one of several auto configuration mechanisms that the printer uses. If you have a DHCP server on your network, the printer automatically obtains its IP address from that server. NOTE DHCP services must be available on the server. Refer to your system documentation or online help to install or enable DHCP services.
6. Select Set up the IP Address Pool. In the IP Address Pool section, set up the IP address range by typing the beginning IP address in the Start Address box and the ending IP address in the End Address box. Also type the subnet mask for the subnet to which the IP address pool applies. The starting and ending IP addresses define the end points of the address pool assigned to this scope. NOTE If desired, you can exclude ranges of IP addresses within a scope. 7.
d. In the DHCP Options window, select WINS/NBT Node Type (046) from the Unused Options list. Select Add to add the node type to the Active Options list. In the Byte box, type 0x4 to indicate a mixed node, and select OK. 11. Click Close to exit to Program Manager. Windows 2000 Server To set up a DHCP scope on a Windows 2000 server, perform the following steps: 1. Run the Windows 2000 DHCP manager utility. Click Start, then select Settings and Control Panel.
c. Enter the appropriate information in each field, including the reserved IP address for your printer. The MAC address for your printer is available on the printer's network configuration page. NOTE d. Under Supported types, select DHCP only, then click Add. Selecting Both or BOOTP only will result in a configuration through BOOTP due to the sequence in which the printer initiates configuration protocol requests. NOTE e. Specify another reserved client, or click Close.
Configuring for LPD printing Introduction The printer contains an LPD (Line Printer Daemon) Server to support LPD printing. This chapter describes how to configure the printer for use with various systems that support LPD printing.
LPD programs and protocols Program Name Purpose of Program lpr Queues jobs for printing. lpq Displays print queues. lprm Removes jobs from print queues. lpc Controls print queues. lpd Scans and prints the files if the specified printer is connected to the system. If the specified printer is connected to another system, this process forwards the files to an LPD process on the remote system where the files are to be printed.
Step 2. Setting up print queues You must set up a print queue for each printer or printer personality (PCL or PostScript) that you use on the system. The printer supports only one type of queue (raw). Therefore, it does not matter what queue name is given as the printer will treat each one the same. The printer treats data from any source as the same and has no provisions for adding carriage returns, tagging binary Postscript data, special PJL sequences, user-defined strings, etc., to the job stream data.
mkdir /usr/spool/lpd cd /usr/spool/lpd mkdir printer_name_1 printer_name_2 chown daemon printer_name_1 printer_name_2 chgrp daemon printer_name_1 printer_name_2 chmod g+w printer_name_1 printer_name_2 where printer_name_1 and printer_name_2 refer to the printers to be spooled. You may spool several printers. The following example shows the command to create the spooling directories for printers used for printing.
10. Click OK and select Exit from the List menu. 11. Select Exit Sam. NOTE By default, the lpsched is not running. Make sure you turn the scheduler on when you set up your print queues. Printing a test file To verify that the printer and print server connections are correct, print a test file. 1. At the UNIX system prompt type: lpr -Pprinter_name file_name where printer_name is the designated printer andfile_name refers to the file to be printed.
NOTE You may need your Windows system distribution files or CD-ROMs to install TCP/IP components. 1. To check whether you have Microsoft TCP/IP Printing protocol and TCP/IP printing support: ● Windows 2000—Click Start, Settings, Control Panel. Then double-click the Network and Dial-up Connections folder. Double-click the Local Area Connection for your network and click Properties.
a. Click Start, Setup, and Control Panel. Double-click the Network and Dial-up Connections folder. b. Click the Advanced menu and select Optional Networking Components. c. Select and enable Other Network File and Print Services. d. Click Details, and verify that Print Services for Unix is enabled. If not, enable it. e. Click OK, and then Next. 2. Open the Printers folder (from the Desktop, click Start, Settings, and Printers). 3. Double-click Add Printer.
7. In the Name of printer or print queue on that server box, type (in lowercase) the name of the print queue desired. Then click OK. 8. Ensure that the port is selected in the Add Printer list of the available ports, then click Next. 9. Follow the remaining instructions on the screen to complete the configuration. Verifying the configuration From within Windows NT, print a file from any application. If the file prints correctly, the configuration was successful.
Configuring a network LPD printer Adding a new LPD printer 1. Open the Printers folder (from the desktop, click Start, Printers and Faxes). 2. Click Add Printer. On the Add Printer Wizard welcome screen, click Next. 3. Select Local printer, then uncheck the automatic detection for Plug and Play printer installation. Click Next. 4.

You may use the Desktop Printer Utility to setup your Mac OS-based computer for LPR printing. The implementation of LPR printing by the LaserWriter 8 driver is compliant with RFC 1179 and should work with any RFC 1179-compliant device. IP printing in LaserWriter 8.5.1 is not available on Mac OS 8.0, but is available on Mac OS 8.1.
8. Click Add. 9. Close the Printer List window.
TCP/IP Introduction This section is intended to provide information to help you gain a basic understanding of TCP/IP. Similar to a common language that people use to communicate with each other, TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of protocols designed to define the way computers and other devices communicate with each other over a network. TCP/IP is rapidly becoming the most used set of protocols.
NOTE When assigning IP addresses, always consult the IP address administrator. Setting the wrong address can disable other equipment operating on the network or interfere with communications. IP address: network portion Network addresses are managed by an organization in Norfolk, Virginia, recognized as InterNIC. InterNIC has been contracted by the National Science Foundation to manage the Internet addresses and domains.
Network class characteristics Class Network Class Characteristics Address Range Maximum Number of Networks in the Class Maximum Hosts in the Network A 0 0.0.0.0 to 127.255.255.255. 126. Over 16 Million. B 10. 128.0.0.0 to 191.255.255.255. 16,382. 65,534. C 110. 192.0.0.0 to 223.255.255.255. Over 2 Million. 254. Configuring IP parameters TCP/IP configuration parameters (such as IP address, subnet mask, default gateway) can be configured on the printer in a variety of ways.
Subnets When an IP network address for a particular network class is assigned to an organization, no provision is made for more than one network being present at that location. Local network administrators use subnets to partition a network into several different subnetworks. Splitting a network into subnets can result in better performance and improved use of limited network address space. Subnet mask The subnet mask is a mechanism used to divide a single IP network into several different subnetworks.
If multiple gateways or routers exist, then the default gateway is typically the address of the first, or nearest, gateway or router. If no gateways or routers exist, then the default gateway will typically assume the IP address of the network node (such as the workstation or printer).
Troubleshooting Verifying that the printer is on and online Check the following items to make sure the printer is ready to print. 1. Is the printer plugged in and turned on? Make sure that the printer is plugged in and turned on. If the problem persists, you might have a defective power cable, power source, or printer. 2. Is the printer READY light on? If the light is blinking, you might need to wait until the current job is completed. 3.
4. Can you "ping" the printer? Use the command prompt to ping the printer from your computer. For example: ping 192.168.45.39 Ensure that the ping displays round-trip times. If you are able to ping the printer, verify that the IP address configuration for the printer is correct on the computer. If it is correct, delete and then add the printer again.
