my 7720 Officejet Pro keeps going offline. I have installed it twice now- Wireless connection.  Getting fed up having to re-install it.  Have reloaded the driver twice now.  It also does not connect to my android samsung flip phone.

Welcome to the HP support community.

I understand that you are getting the offline error, I am glad to assist you.

Use HP Print and Scan Doctor to fix connectivity and printing issues.

Download HP Print and Scan Doctor.

• Run HPPSdr.exe from the download location on your computer.
• Once HP Print and Scan Doctor opens, click Start, and then select your printer.
• If your printer is not in the list, turn it off and on, and then click Retry.
• If there is a connection problem, follow the instructions in HP Print and Scan Doctor.
• If a screen prompts you to turn on printer updates, click Yes.
• If a screen prompts you to make your printer the default printer, click Yes.
• Try to print.

.Assign a manual IP address to manually connect the printer.

Find the printer IP address to assign it manually.

• Make sure there is U.S. letter or A4 size, unused, plain paper in the input tray.
• On the printer control panel, swipe down to open the Dashboard, and then touch the Setup icon .
• Swipe up on the display, and then touch Reports.
• Touch Network Configuration Page.

Setting a Static IP Address

Once you know your printer’s IP address from the page you printed, entering it is pretty easy. Here’s what you do:

1. Run your Web browser.
2. In the Web browser’s address bar, type the IP address of your printer and press Enter. Assuming you entered the right address, the HP printer control panel should appear.
3. Click the Networking tab.
4. Under Connections, click Wireless.
5. Under IP Address Configuration, click Manual IP.
6. Enter the IP address, subnet mask, and default gateway in the appropriate boxes.
7. Click Apply.
