HP Laserjet 2015dn (network printer) does not print. Cannot ping it's appointed address anymore, therefore cannot open a web page to it.

Press and hold the green button for few seconds

INSTALLING A NETWORK PRINTER These instructions generally apply to all network printers with built-in network cards (print servers) such as HP LaserJet printers, IBM Infoprint laser printers etc. This example is for a network HP LaserJet printer. To install a HP printer (with built-in Jetdirect print server) as a network printer on a wireless network . You need to do the following -
1. Open the printer\'s menu and enable the Network Card - these print servers use a static IP address therefore, configure the IP address of the network card so it matches the IP range of your network. Eg. If your IP\'s are 192.168.0.xxx then set the network card to a high number say 100. (This is to prevent a conflict with the router issuing the same IP address to a computer on your network). Then set the Subnet Mask IP address to 255.255.255.0 If you have a wireless router then check the IP address range that the router issues to the computers on your network and configure the static IP address in the printer\'s network configuration accordingly.
2. Install the HP printer driver on your computer/s using the LPT printer port.
3. Connect the printer with a LAN cable to the network hub/router.
4. Click on Printers and Faxes - right click on the HP printer and click on Properties.
5. Click on Ports and click on Add Port.
6. In available ports - click on Standard TCP/IP Port and then Configure port.
7. Tick the IP box and type in the IP address of the HP\'s printer IP address.
8. Click OK and tick Enable bi-directional support and then OK
9. Remove the printer cable, then do a test print to see if the printer prints correctly.
Install the HP printer driver on every computer on your network and configure the printer\'s TCP/IP port as previously detailed. Do a test print page to check the printer.
You can now print from any computer on your network.

Hi Basically I powered up the printer unplugged the network cable. Reconnected and waited 2 min. Pressed green button till first sign of green light flashing. The printer then printed out a printout which shows ip address on first and third page. I then used internet explorer to change printer from DHCP settings to fixed. just type new ip address on internet explorer address line. PC and printer must be on same network.

Hi How to check the print server is in the wireless network or not!! Check under the Router Setup page Router's ip address... Check if you are able to ping the Print Server Ip address....Since it the router will assign a ip address from DHCP range.. If you are able to ping the router's ip address and the print server ip address then the print server is in the Wireless LAN... Try the following steps. 1. Go to run and type "cmd" press enter 2. type ipconfig. 3. Check the range of ip address...if its 192.168.0.XX 4. Try pinging that ip address.. 5. If able to ping the router and print server.. Then the wireless network is fine... Somehow some of the printer's don't work with some of the print servers.. Check if D-link does support the printer or not!!!! for this particular model of the router...
