Connect the printer power cord to the printer and turn the printer back on. Disconnect the power cord from your wireless router. Wait 10 seconds before reconnecting it. It may take a few minutes for your internet to come back on.
To access the latest user guides or manuals for your product, go to http://www.hp.com/ support, and select your country. Select Find your product, and then follow the on-screen instructions.
You may see a “printer offline” error if your computer can`t communicate with your printer. This can be caused by loose cable connections or an outdated printer driver or operating system. The HP Smart app (below) can automatically diagnose and resolve printer offline issues in Windows operating systems.
On the printer`s product page, under Self support, select Manuals. Download the appropriate manual.
Click Start, System Information, then Help and Support and then System Information. Alternately, click Start, type system in the search field, and then select when it appears in the program listing. Alternately, hold the function key and press Esc. The System information window displays to show basic information.
Check for Loose Cables and Network Connection

A temporary power outage, even one that lasts only a few seconds, could have been enough to knock your wireless router off the network. Rebooting or otherwise resetting the modem or router should fix the problem and bring the printer back online.

This can be caused by an error between the device and the printer. This can be as simple as a disconnected cable, or an tryerror occurring due to a paper jam. However, it can also indicate a problem with your driver or software.
For the most part, a printer will appear “Offline” if your computer is unable to establish communication with the device. This could be due to factors like loose cable connections, outdated printer drivers, problems with important system services, etc.
Right click on the printer icon and select “Open Devices and Printers.” Check if your printer is offline.
To attempt to get your printer online. Go to “Settings” and then “Printers.” Right-click on the printer and select “Use Printer Online.” Check to see if there are any print jobs and clear them.
Restart the printer and the computer or mobile device to clear possible error conditions. Restore Wi-Fi setup mode. Most printers with a touchscreen display or menu: Open the Wireless or Setup menu, select Network setup or Settings, and then select Restore Network Settings.
