HP OfficeJetPro 7720 offline

[Pietari11]

I try to print on my HP 7720 A3- printer. This is impossible almost all the time as the printer is offline. Then I have to fiddle with HP Print and Scan Doctor to get the printer back alive. 10 minutes later I want to print more and it's again offline. There are many other printers in my network and they are not offline all the time.

I previously had a similar HP A3-printer (OfficeJet 7500A) and it went offline sometimes but not as often as 7720. I was kinda hoping that this issue had been solved in 8 years.

Is there a simple and quick way to bring back the printer online? ...and a way to keep it online all day?

Computer: Windows 10 (64)

Router: Zyxel

Other than that I'm quite happy with the new printer.

Hey there! @Pietari11, Thanks for stopping by the HP Support Forums!

I understand your printer goes offline constantly.

Don't worry I'll try to help you out.

Did you make any changes to your printer?

Does the issue persist when you make a copy from your printer?

Is the printer connected to wired or wireless connection?

Try assigning a static IP to your printer and check if it helps. Try the steps recommended below.

Print a Network Configuration Report or Wireless Test Report from your printer.
If your printer has a control panel with a display, print the report from the network settings or network setup menu.
If your printer does not have a display, print the report using the buttons on the printer control panel. For many HP printers, this is done by pressing and holding the cancel button or a combination of buttons on the control panel until a report prints. For more information on how to print a report for your printer model, see the User Guide or search the HP website for network configuration report and the model of your HP printer.
On the report printout, look at the network status for your network connection type (wired or wireless.)
If status is connected, continue with these steps.
If status is anything other than connected, such as Off or Disabled, then the printer is disconnected from your network. This is the reason your printer is offline. You must connect the printer to your network before you continue. For more help on how to set up a connection to your network, see the User Guide, search the HP website for your printer model and wireless or wired network install, or use the wireless setup wizard from the control panel of your printer if available.
On the report, find the IP Address, subnet mask, and Default Gateway for your active (connected) network connection type. If your report has separate numbers for IPv4 and IPv6, then use the numbers listed in the IPv4 section.
From a computer connected to your network, find the URL(s) for Embedded Web Server (EWS) on the report and enter the URL into your Internet browser. If the webpage appears blank, use a different Internet browser.
Click the Network or Networking tab, and then open the section or page for your network type: wired or wireless.
Click Manual IP.
If you see a Suggest a Manual IP Address button, click Manual IP address, and the Manual IP addresses are automatically filled out for you.
If your page does not have a button to suggest a manual IP address, type the IP address, subnet mask, and default gateway using the numbers shown in the report you printed.
Write these new numbers on a piece of paper. You might need to use them later when adding a second printer device.
Click Apply, and then wait until the changes are confirmed.
 
Also, uninstall the printer drivers from root level and install the full feature printer software.
 
In Windows, search for and open Programs and Features.
Select your HP printer.
Select Uninstall.
In Windows, search for and open Devices and Printers.
In the Devices and Printers window look for your HP Printer. If you see it listed, right-click on it and choose "Delete" or "Remove Device.”
Open up the run command with the "Windows Key + R" key combo.
Type printui.exe /s and click OK.
Click on Drivers tab.
Look for HP Printer driver. If you see it click on it and click remove at the bottom.
Select OK.
