Mac computer won't talk to HP printer. Have gone through setup and was printing earlier but not now.

My Mac keeps saying the printer is offline. I think I've done everything I can do to get it back online. It's wireless.

Hi @KathleenMac2,

Welcome to the HP Support Community

I understand you are facing a connectivity issue with your HP printer. Not to worry I will help you to get a resolution to resolve the issue.

To assist better:

• May I have the exact model name of the product? Refer to this document for steps to find the product details. Do not share any of your personal information such as serial, phone number, email ID, etc. 
• How far is the printer located from the WiFi router?
• Restart the router, the printer, and the Mac
• Make sure the printer and the Mac are connected to the same wireless network. Either 2.4 or 5GHz network.
• If you have a dual-band router and both 2.4GHz and 5GHz networks share the same name/SSID, the printer will not be able to connect to the network. In this case, contact your Internet service provider to assign different names to both networks.
• Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'.
• Bonjour locates devices such as printers, and other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems. 

While you respond to that, Let's Restore Wi-Fi setup mode on the printer

• Prepare a printer for a Wi-Fi connection by restoring the Wi-Fi setup mode.
• When the settings are restored, the printer enters Wi-Fi setup mode for about two hours, making it discoverable during the HP software installation.
• Most printers with a touchscreen: From the Wireless or Setup menu, select Network setup or Settings, and then select Restore Network Settings.
• Most inkjet printers without a touchscreen: Press and hold the Wireless and Cancel buttons until the Power button flashes, and then wait for the Wireless light to flash.
• Once you restore the network to defaults, then please follow the instructions on this link to connect the printer back to your PC.

Once you connect the printer on wireless you may try using the Airprint feature as well. 

Add the printer using Apple AirPrint drivers.

1.) Click the Apple menu, click System Preferences, and then click Print & Scan or Printers & Scanners.

2.) Check if your printer name displays in the Printers list, If your printer is listed, click the printer name, click the minus sign to delete the printer.

3.) If you see multiple printer queues for the same printer, remove all extra printers by selecting them one at a time, and then clicking the minus button at the bottom of the list.

4.) Click the plus sign click Add Printer or Scanner, click the printer name.

5.) Click the Use or Print Using menu, select AirPrint in the pop-up menu. Then click Add.

6.) Try to print.

Hope this helps! Keep me posted.
