I need my wifi factory reset

[KJRider1]

I need to reset my 2549 All-in-One Printer's WiFi to factory reset so that I can connect and print from my phone which is a Samsung AO3s. Every time I try using all the correct password and info the WiFi will not connect the printer and gives a "incorrect password" error

If the printer is connected properly to the router then you should have no problem printing from the phone.

You are asking to reset the printer. I was unable to find any type of factory reset other than unplugging from wall.

I assume you then want to use Wi-Fi direct to print directly from the smartphone to the printer and not bother going through the router.  if so, your phone must use the 2.4ghz band as the printer does not use the 5 or 6.

Try connecting the printer to the router. 

Wi-Fi connection

Ideally, your Wi-Fi printer should connect to the modem or router. If your network has multiple boosters / repeaters, it is possible the printer may connect randomly to any of the units. The modem needs to provide the same IP address on every connection. This rarely happens with random connects. An alternate Wi-Fi connection is Wi-Fi direct. Your laptop or smartphone prints directly to the printer and does not go through the modem.

This video shows how to connect to the router: 2549  Wi-Fi Direct is explained on page 16 of the User Manual, this Wi-Fi setup avoids configuring the modem.

Software

HP updates software periodically. Downloads shown below may be old. You should always visit the Software and Download page to look for new releases. You may need to select an operating system (OS) first. If windows 11 is missing then use 10. You can go as far back as Windows 7, 64bit to get missing drivers. After selecting the OS click the blue Open all button to view all downloads.
