[gg0923]

I have new router and now can't get printer to connect to WiFi network, when scanning for WiFi network receive message can't connect to WiFi.  I've tried using the H P smart app, have reinstalled app and doesn't help, tried to add from Mac system preferences and printer doesn't show up.  Could use advice of how to repair this problem.

Thanks

Hi @gg0923,

Welcome to the HP Support Community

I understand you are facing a connectivity issue with your HP DeskJet Plus 4155 All-In-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

To assist better:

• 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.

While you respond to that, Let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle

Restore Wi-Fi setup mode on the printer

• 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.
• Update printer firmware & Update software on Mac 

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.
