My hp laserjet p4015n is connected directly to the network via ethernet however i can't locate the printer and add it through control panel or even by running its ip address

Troubleshoot the wired network connection
Make sure you are using an undamaged Ethernet cable, check for a green light near the Ethernet port on the printer, and then print a report to verify the connection.
Turn off the printer, and then disconnect the Ethernet cable from the router and the printer.
Check the cable for damage, and then verify that it is an Ethernet cable and not a phone cable.
NOTE: Ethernet and phone cables look similar, but Ethernet cables are usually bigger and have eight visible wires on the connector.
Reconnect the cable to a different Ethernet or LAN port on the router, and then connect the other end to the printer's Ethernet port.
Turn on the printer.
Check the lights on the printer's Ethernet port to make sure the connection is successful. The green light should be steady, and the orange activity light should blink.
Print a Wireless Network Test Results or Network Configuration report.
Inkjet printers with a control panel menu: Open the Wireless, Network Settings, or Setup menu to locate the list of available reports.
Most inkjet printers without a control panel menu: Press the Wireless and Information buttons at the same time, or press the Wireless and Start Copy Black buttons at the same time.
LaserJet printers: Press and hold the Wireless button for 10 seconds or until the Ready light blinks, or go to the Wireless menu and select Wireless Network Test.
Laser NS and Neverstop Laser printers: Press and hold the Resume and Wireless buttons for 3 seconds.
DeskJet 6000 and 6400, ENVY 6000 and 6400, and Tango printers: Touch and hold the Information button until all control panel buttons light up, and then touch the Information and Resume buttons at the same time.
Make sure the Network Status is Ready, or follow any instructions to resolve network issues identified on the report.

the card may be faulty or not installed correctly. go over the connection and make sure everything is installed correctly. if that doesn't work, try a new card.

put the printer on
connect a straight cable from printer to your switch in network
now read the instruction manual the default ip is written over there
note it
now from any system in network
open network connections click on properties
goto tcp/ip
click properties
click advance
in tab-ip setting add any other ip of same class which was printer's default ip
ex- if printers ip was 192.168.0.1 add 192.168.0.7
now apply all settings
now on the same computer type the printers ip in any browser
this will give the access of printer to you
change ip setting according to your network class
i.e. assign the printer your network class ip
now you can access the printer from any system in network
do one thing that put drivers of printer in some sharable drive on the network
now you can goto any system add printer from control panel
select network printer
select the printer

when prompted provide location of drivers of printer
you are done .

You can change the paper type settings using the control panel on the printer.

Thank you for contacting FixYa with your inquiry.
This printer can work very well via a standard printer cable directly connected to your computers LPT Terminal. Most of Microsoft's current Operating Systems already have the LaserJet J2300 drivers built in and will automatically install when connected.
To confirm your connection to go to your computers printer setup and ensure the driver is configured to print from LPT1 port and click on print a test page. (Start/Settings/Printers/LJ2300 - Right Click on properties then click on the tab for ports. The general tab should have a button to print test page)
The network card that comes with your printer (Jet Direct Card) will not be used with this method nor will the Ethernet cable be required.
Hope this helps helps. Please keep us updated and remember to rate this answer.

1.Position the printer near your wireless network's router. Plug an Ethernet cable into the Ethernet port on the back end of the printer. Run the other end to any of the numbered ports on the back side of the router. Press the "Print Report Page" button on the printer.

2.Navigate to the setup page listed on the report page and click the tab labeled "Networking."

3.Scroll to the "Connections" heading and click "Wireless." Navigate to the tab labeled "Wireless Setup." Click the "Start Wizard" button.

4. Follow the prompts to connect the HP 1012 to your wireless network. Click "Finish" and close the browser.

5.Open the "Start" menu and navigate to "Network." Choose the "Add a Printer" option. Click "Add a network printer."

6. Click "HP Laserjet 1012" and choose "Next" and "Finish" to access the printer through your computer's wireless connection. Repeat the process of adding the printer on any other computers on the wireless network.

Please follow these steps and let me know if it works or not

Can you ping the i.p. for the printer

To use a network printer directly on a PC (including a laptop) without being plugged into a hub, or switch, you will need to use a CROSSOVER ethernet cable.

You will also need to know (or set) the IP address of the printer (this will be on a page when you do a configuration page directly from the printer menu system).

You will also need to set you PC (or laptop) to have an IP address in the same address range, and subnet mask.

The LaserJet 2600N has a built-in print server and can be connected to the local network (normal ethernet cable) directly. While printer sharing via Windows should work, I found it much more convenient to access it without the need of a hosting computer - you do not need to switch on the desktop PC for printing from the Laptop, for example, its also printing faster.

The last time I checked, you cannot set up a local printer using a TCP/IP port. A local printer is physically connected to a computer via a parallel, serial (very old), or USB cable. If the printer is connected to a switch, hub, or router via an Ethernet cable, it is by definition a network printer and the driver install must reflect this. I don't understand why it is able to print out the test page after the install. If you open up Control Panel -> Printers and double-click on the HP Laserjet 2600n in there, it will bring up the local spooler for the printer. You may have a bunch of print jobs queued up in there that it cannot currently send to the printer. You may want to clear the queue first (cancel all print jobs). Let me know if you have problems clearing the queue & I can give you instructions on how to do that one too.
