Hi @Candy261

Welcome to the HP Support Community.

 I understand that your printer shows offline. I'd like to help!

Follow the steps below. 

A printer status of "Offline" displays on the computer and the printer does not print.

Figure : Printer status "Offline" in Devices and Printers

• When the printer status is "Offline," it indicates that the computer cannot communicate with the printer. This issue can occur for various reasons, such as the following:
• The printer is turned off
• The network cable or USB cable is disconnected
• The printer is set to "Use printer offline"
• The following symptoms might also be present:
• The printer does not respond
• The printer icon(s) status is offline or greyed out
• The default printer driver has been changed
• Unable to find printers or other devices on the network
• File and printer sharing is disabled
• Network port IP address changed or is reset
• The network loses connection with the printer after it enters sleep mode

Please go through the document for the remaining steps. 

Hope this helps! Keep me posted.
