HP Photosmart 5510 repeatedly says its offline when I try to print

[Hippielaundry]

I am running a business in my camper and have used this printer wirelessly and successfully for years in my home office. Now that I am trying to print on the go, it is saying the printer is offline. I have tried printing from my MacBook, iPad, and phone, but each time it tells me the printer is offline. The actual printer itself says it is connected to WiFi , ran the report and everything looks good, but for some reason it will not connect to my devices to print the documents I need.  I have tried unplugging it and starting over, and I have tried connecting to different WiFi’s. SOS. I’m at a loss and really need this printer for my traveling business. Thank you!

Welcome to HP Support Forums.

I came across your post and would like to assist you.

I understand that you're unable to print HP Photosmart 5510 e-All-in-One Printer from your Macbook, iPad and the phone. The printer appears offline. 

You have done a remarkable job in troubleshooting this issue.

Here are a few things you may check to ensure that the wireless printing works well:

• Verify printer and Mac connected to same network that is not public WiFi or Guest network.
• The printer should be connected to 2.4 GHZ network.

Let's ensure that the printer is well connected to the network. Please perform the following steps in the given order:

• From the Home screen on the printer display, touch the right directional key, and then touch the Wireless icon.
• Scroll and select "Restore Network Defaults".
• Select Yes.

If the printer was connected to the wireless network then it will disconnect now and the wireless setting will restore to defaults.

Now, let us re-run the wireless setup wizard to have the printer connected to the wireless network:

If the printer still does not print from your Mac and iOS devices.
Step 1: Check connection between the printer and the Mac (connectivity)

1. Make sure the printer is idle, not making any sounds, before continuing.

2. With the printer turned on, disconnect the power cord from the rear of the printer.

3. Unplug the power cord from the wall outlet.

4. Wait at least 60 seconds.

5. Plug the power cord back into the wall outlet.

6. Reconnect the power cord to the rear of the printer.

7. If the printer does not turn on by itself, press the Power button  to turn it on.

8. Try printing again and note what happens.

   • If the printer prints, you can stop troubleshooting.

Step 2: Remove multiple printers from the printer list

Check for multiple devices in the Printers list, and then remove any extra entries other than one in idle status.

1. Search the Mac for Print, and then click Print & Fax, Print & Scan, or Printers & Scanners in the list of results.

2. Find the printer names that match your printer from the list of devices.

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. Leave one 'idle' printer in the list that matches your printer if available and use this printer as the Default printer.

4. Try printing again.

   • If the printer prints, you can stop troubleshooting.

   • If the printer remains offline or displays an error, continue to the next step.

Step 3: Delete the existing print queue and add the printer

Remove the printer queue from the list of printers, and then add it again. Doing so creates a new printing session.

1. Make sure your Mac is connected to the Internet.

2. In the Printers list, click your HP printer, and then click the Minus button  to delete it.

3. Click the Add button .

4. Find and select the name of your printer from the Printer list, and then click Add to add your printer. Do not select an HP Fax driver.

      NOTE: If your printer does not display in the list, make sure the printer is connected, turned on, has power, and is ready to print.

5. Click Print Using or Use.

6. Select AirPrint.

   Your new printer queue displays in the Printers list in an Idle status .

7. Try printing again.

   • If the printer prints, you can stop troubleshooting.

Also, in your free time, you may refer to this HP document for additional steps if the issue persists. 

I genuinely hope this fixes the issue. Feel free to keep me posted.
