Restart the printer and the computer or mobile device to clear possible error conditions. Restore Wi-Fi setup mode. Most printers with a touchscreen display or menu: Open the Wireless or Setup menu, select Network setup or Settings, and then select Restore Network Settings.
Your printer should have been packaged with a USB cable regardless of whether it is a wireless or wired printer. Plug the cable into your printer and your computer`s USB port. The direct linking should trigger your computer to recognize the printer and start up the software needed to complete the installation.
If you`re using a wired printer, make sure that the printer cable is properly connected from the printer to your PC. For wireless printers, check the wireless connection. Make sure the printer`s wireless option is turned on and available.
The printer is either low in toner, the density is set too low, or the Economode may be turned on. Remove the toner cartridge and shake it. This will redistribute the toner and often will temporarily solve the problem. However, this usually indicates it is time to install a new cartridge.
Make sure your Wi-Fi network and printer setup meet connection requirements. Restart the printer and the computer or mobile device to clear possible error conditions. Make sure the printer is not connected to a computer with a USB cable.
Press the WPS button on your wireless router. Press and hold the Wireless button on the product control panel for two seconds. Release the button when the wireless light starts blinking. Wait up to two minutes while the product establishes a network connection with the wireless router.

To fix the error code 0x0000011b related to networked or shared printers, Microsoft says you should disable the print spooler privacy settings on both the Client PC (from which you work) and Print Server (Workstation to which the printer is attached).
The only permanent solution to the 0x0000011B error is to install the latest Windows Update which fixes the issue. For now, you can try uninstalling the update or disabling the problematic security feature from the Registry. Other workarounds include installing the printer manually.
Turn the product on while you press and hold the Resume button for 10-20 seconds. The Attention light turns on. Release the Resume button. The Attention and Ready lights cycle while the product restores factory defaults.
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.
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.
Instead of adding the printer to the existing network, you may attempt to print via Wi-Fi Direct. In case this does not work as well and you refuse to use HP Smart, it`s on you to bring the right drivers and install them manually.
From the Home screen on the product control panel, touch the Setup button. Scroll to and touch the Network Setup menu. Touch the TCP/IP Config menu, and then touch the Manual button. Use the numeric keypad to enter the IP address, and touch the OK button.
Connecting using a network key or PIN

If your printer doesn`t have WPS, you`ll probably have to enter a `network key` – a series of numbers and letters – into the printer using the function buttons and screen on the printer in order to establish the connection between your printer and router.

Open HP Smart app, click your printer, click Printers in the top menu bar, and then click Diagnose & Fix. Follow the instructions if any issues are found. If you still can`t print, remove and re-add the printer.
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.
In Windows, search for and open Add a printer or scanner . Click Add a printer or scanner, and then wait for Windows to locate available printers. If your printer is found, click it, and then click Add device to complete the driver installation.
