To resolve this problem, I’ve provided every single possible solution for you. If you don’t find any solution after that, then directly concern the helpline.
Why Is My Wifi Light Blinking Blue On HP Printer
If your printer is blinking blue light, it means that the printer has lost connection with your router and you can’t use the wireless printing until you have reconnected with the internet.
To solve any kind of problem, we must know why it occurred and that’s why I have pointed out all the possible reasons why there is a blue light on the HP printer.
Reason 1: Slow Wifi

Sometimes because of the weather or some other connection issue, you see that your WiFi is too slow. This is when you’ll see that there is a blue light blinking on your printer head.
So, it’s completely clear that you need an active and pretty fast wifi connection to keep your device connected to the printer.
Reason 2: Wireless Network
The problem occurs when trying to connect to a wireless network. When you buy a new printer and try to connect it to your computer, make sure it is not connected to another printer. If your computer is connected to other printers, then the new one will not be able to connect because there is no room left.
In this situation, the printer blinks blue to indicate that it is facing a problem connecting to your laptop. So, to stop the blinking, first, disconnect all the printers and try to connect again.
Reason 3: Wifi Router is Too Far
Where is your Wifi router? Is it too far from your printer and laptop? Remember that when your router is too far, it does not catch the proper Wifi signals because of the frequency.
Therefore, if you move your router too far from the printer the connection will break and the printing process will stop. In this situation, the printer starts blinking with blue light indicating that the connection is being disrupted.
Reason 4: Outdated Firmware
The software that connects the printer and the laptop is called Firmware. Every time, the software is updated, companies make sure to add varieties to them. All of these things are not automatically done.
Updating them manually is what you have to do. It can be difficult to communicate with your latest laptop or PC when the printer’s firmware is outdated. So, another reason for the blinking blue light is to keep using outdated firmware.
If you do not upgrade the software of your printer more often, soon there will be a service call error which will indicate by blinking all light on printer.
Reason 5: Printer Gone Sleep Mode
The latest printers have advanced technology. When you don’t print and the printer isn’t on, it automatically goes to sleep.
It blinks with the blue color of light when you suddenly start printing it. What happens is the printer is not fully switched on after being in sleep mode. Wait till the printer reconnects with your router and the blue light blinking stops.
