Hey There, I am Sofia Carter. You have been working for 10 hours continuously. You’re astonished to see an error when you try to take out a printout. You may start thinking, why is my hp printer is offline? Don’t worry. It can happen due to a network connection. Check whether your printer is connected to the router properly. The connection between the printer and the router should be through a cable or wireless communication. If there is any problem with a loose connection, then remove and reconnect the cable. See whether your printer can identify the router wirelessly if you are using a wireless connection.
