Cannot connect hp Laserjet Pro M12W to the wifi

[Cathy111]

I moved to a new place recently, and updated the wifi user name and password under Networking.  I can connect to my printer through USB cable but I just cannot connect to the printer through Wifi.  I followed the instruction regarding how to update Wifi name and password.  However, when I tried to add the printer to the wifi, the printer didn't pop up when I click +

When I tried to reset the printer using the driver that I downloaded on hp support, I didn't see any option of setting up wifi printer.  

Can anybody help on my issue?

Thank you

Hi @Cathy111

Welcome to the HP Support Community. 

Try re-installing the printer driver - 

1. Disconnect the USB cable from the printer, if necessary.

2. Click Finder in the Dock.

3. In the menu bar, click Go, click Applications, and then open the HP or Hewlett Packard folder.

   • If HP Uninstaller is in the folder, double click it to uninstall the software, and then skip to the step to prepare the printer for the driver installation.

   • If HP Uninstaller is not in the folder, continue to the next step.

4. Click and drag the HP or Hewlett Packard folder to the Trash icon in the Dock.

5. In the menu bar, click Go, click Go to Folder, type /Library/Printers, and then click Go.

6. Click and drag the HP or Hewlett Packard folder to the Trash icon in the Dock.

7. Right-click or Ctrl + click the Trash icon, and then select Empty Trash.

8. Prepare the printer for the driver installation. Make sure it is turned on, cartridges are installed, and plain paper is loaded in the main tray.

9. Go to 123.hp.com. This guided service automatically locates the correct print driver or app for your computer operating system version.

10. Follow the instructions to download and install the driver or app. During the installation, select HP Smart or the full software option to get the most out of your HP printer, and then follow the steps to set up the printer connection.
