Hi @Chavlene,
Welcome to HP Support Community.
Thank you for posting your query, I will be glad to help you.
I understand that there is a blue light blinking on your HP DeskJet 4155e All-In-One Printer. Do not worry, there is nothing wrong with your printer. The blue light symbolizes “wireless connectivity”. If the blue light is blinking, it means that the printer is trying to connect to a wireless network. You can turn it “off” since you are connected directly to the laptop.
Touch the wireless icon – settings – Turn off the wireless feature. You will notice that the light is now turned off.
Please let me know how it goes!
I hope this helps.
Take care and have a good day.
