Well, with the old network card still in the machine you can print a configuration page (on HP printers) or a Network status page (on Lexmark printers). How do I know what IP address to use for the HP laser printer? Once the data leaves one address, it travels across the network to its destination address and delivers the information to the correct address. They have a destination address, a return address, and the information inside it. Networks communicate with each other in the form of packets. The device used acts as a traffic coordinator to help the packets of data get from point A to point B in the most efficient way possible. The gateway can be a computer, a router or a modem. The gateway NETWORK is the bridge from the LAN (Local Area Network) to the WAN (Wide Area Network). The gateway is the connection that the Subnet Mask and IP addresses use to connect to the outside world. The Subnet Mask allows you to add more computers to the same gateway. Think of it as adding another street to the city. This allows you to connect more computers to a network by sub networking. You can have multiple Subnet Masks on the same gateway. You can have two IP addresses that are the same, only if they are on a different Subnet Mask or gateway. If you have duplicate IP addresses on the same Subnet Mask and gateway, it will cause mass confusion from the host server or the router. This causes problems, similar to a network.

You can have multiple houses on a street and many streets in the city but you cannot have duplicate house addresses on the same street.

The IP address is the house number, the Subnet Mask is the street, and the gateway is the city. What do all the numbers and abbreviations mean? Think of a network address as a house address. We will only cover the TCP/IP portion of networking since it is the most common.

Unfortunately since networks are dependent on how the IT person sets them up, we cannot go into detail on what IP addresses, Subnet Mask, and gateways to use. Setting up a laser printer network card is fairly easy to do once you have the addresses The majority of them are due to the card being set up incorrectly. So you may be asking why the printer doesn’t print from the network card? There could be many reasons as to why this happens. Surprisingly, this happens to a lot of HP printer technicians and creates a lot of unnecessary warranty returns. You install the new card, plug it in to the network and the lights on the network card appear to be functioning properly. Imagine this scenario you go to your customer’s HP laser printer to replace the network card because it failed. JetDirect Network Cards Not Working?Make Sure The Network Recognizes The Printer
