HP OfficeJet Pro 7740 Connection issues

[123NS]

I have an HP OFFICEJET PRO 7740 that can not be found on the network.  The printer says it's connect, all test results from printer test thru printer pass.  Worked yesterday, now today nothing....  I have done ALL the troubleshooting listed online, but can't find out how to do a factory reset on the printer itself.  This printer is ONLY 1 week old....

@123NS, Welcome to the HP Support Community!

• How far is the printer located from the WiFi router?
• Make sure the printer and the MAC are connected to the same wireless network.
• This printer supports only 2.4GHz network.

For now, let us try these steps to resolve this issue:

Update the printer firmware

Click here to know different methods of updating printer firmware.

Restart your network devices

1. Turn off the Router, Printer, and the computer/ mobile devices.
2. Wait for 60 seconds.
3. Turn on the Router first and wait for all the lights to stabilize.
4. Turn on the printer and allow it to configure itself.
5. Turn on the computer/ mobile devices.

Reset the network settings and connect the printer to the network

On the printer screen, go to Setup > Network > Restore network settings

Go back to Network menu > Wireless > Wireless setup wizard > choose your network

Now, check the connectivity between the printer and the MAC

1. Obtain the IP address of the printer by clicking on the Wireless icon on the printer
2. On the MAC Go to Spotlight > search for Network utility > select Ping tab > enter the IP address of the printer in the box
3. Check the second box that says Send only > 10 pings
4. Click on ping > Check the results at the end if any packets are lost
5. Note: There should be 0% packet loss, share the results in your next post.

Let me know how this goes.

Kumar0307,

I did everything you said, but still can't see the printer via the Mac.  I can see it connected to the WIfi via the LCD Screen on the printer and when I go into the router utility, but will not stay connected. 

As far as your other questions....

2'

They are, only one network

Yes, 2.4 not 5

Not update needed

All off, then back on

Reconnected to Router

Below is results of the PING test...

Ping has stated…

PING 192.168.1.11 (192.168.1.11): 56 data bytes

Request timeout for icmp_seq 0

Request timeout for icmp_seq 1

Request timeout for icmp_seq 3

ping: sendto: No route to host

Request timeout for icmp_seq 4

Request timeout for icmp_seq 6

--- 192.168.1.11 ping statistics ---

10 packets transmitted, 0 packets received, 100.0% packet loss

Guess I need to just take it back as noting seems to correct the issue.

The PING test shows that the MAC and the printer are not connected to the same wireless network.

• Do you have any Anti-virus software installed on your MAC?
• The wireless status menu on your Mac should also give us quite a lot of information that would help us identify the issue. You can press and hold the option key on your keyboard and click the WiFi icon to get detailed information.
• You can press and hold option-click the WiFi icon and then use shift-command-5 to take the screenshot and share it in your next post. Press the space bar when the icon turns into a camera.

Keep me posted.

Here is the screen shot of the wireless icon.

No Antivirus.....

Here is also a screen shot of the router connected devices showing it connected.

Is this is a Hotspot connection you are using?

Note: HP printers may not work in a Hotspot environment.

Have you tried connecting the printer and the MAC to a wireless router and check how it responds?

Also, check if the router can forward Bonjour packets.

Bonjour locates devices such as printers, 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.

Keep me posted.
