On the printer control panel, press the OK button to display the Home screen. Use the arrow buttons to navigate to and open the following menus: Setup → Network Setup → General Settings. On the General Settings menu, select Show the IP Address, and then select Yes to display the printer`s IP address or host name.
To change your printer IP address, type its current IP address into the address bar of a web browser. Then go to the Settings or Network page and change your printer`s network to a static/manual IP address. Finally, type in the new IP address.
That IP address just means you are not connected to your router in order to get a valid IP address. Suggest you reset the printer back to Network Defaults and run the Wireless Setup Wizard from the front panel to connect to your routers SSID with password.
In the Devices and Printers window click on Add a printer. Choose “Add a local printer or network printer with manual settings”, then click Next. Select Create a new port and choose Standard TCP/IP Port, then click Next. Under Hostname or IP address: Type in the IP address of the printer you intend to connect to.
Connection over the internet:

Enter “what is my ip” into the search bar of the browser, then write down your public IP address (not to share it with anyone else in case of security issues). Step 2. Enter the IP address of your router in a web browser once it is open. Then a privacy warning will appear.

Resetting the HP Jetdirect to factory default settings

The factory defaults include a TCP/IP address of either 169.254. x.x or 192.0. 0.192.

Automatic Private IP Addressing (APIPA) is a feature in operating systems (such as Windows) that enables computers to automatically self-configure an IP address and subnet mask when their DHCP server isn`t reachable. The IP address range for APIPA is 169.254. 0.1-169.254. 255.254, with the subnet mask of 255.255.
The factory defaults include a TCP/IP address of either 169.254. x.x or 192.0. 0.192. Some print servers may show the TCP/IP address as 0.0.
That means, your printer is not configured with a static IP address, but is assigned an IP address automatically by your wireless router.
The factory defaults include a TCP/IP address of either 169.254. x.x or 192.0. 0.192. Some print servers may show the TCP/IP address as 0.0.
From the Home screen on the printer control panel, touch Reports. Touch Configuration/Status Pages. Touch Configuration Page, and then touch Print to print the Configuration and Jetdirect pages. If the printer is connected to a network, find the IP address on the Jetdirect page.
On the computer, in the bottom right corner click on the wireless icon and select the printer from the list to connect to. Then open Internet Explorer and type in the IP address (192.168. 223.1) for the printer in the address bar.

What repair needs to be done for a "50 needs repair" message on an HP Laserjet IIIP?
ANSWER : I don’t know what you mean by good toner cartridges. They haven’t been built in about 10 years, so if they are new OEMs in the box, they are guaranteed to fail. The 50 error on that printer is mostly a burned out fuser lamp. This site was sold, so as you can see, there are no more kits available.
