@2905, Hello and welcome to the HP Support Community!
Thanks for posting your question. I'm here to help you get things back on track.
I understand how frustrating it can be when your printer shows a "Printer Offline Error Code 45" along with alternating blue and orange lights. Let's work together to get this resolved.
Power Reset the Printer
This helps clear any temporary hardware or communication glitches:
- Turn ON the printer.
- Remove the ink cartridges carefully.
- Unplug the power cord from the back of the printer and the wall outlet.
- If connected via USB, disconnect the USB cable as well.
- Wait for 2–3 minutes.
- Press and hold the Power button on the printer for 30 seconds to discharge any residual power.
- Plug the power cord directly into a wall outlet (avoid surge protectors).
- Reconnect the power to the printer and turn it on.
- Reinsert the cartridges once prompted.
Update Printer Firmware
Outdated firmware can cause communication issues:
- Visit the HP Support page.
- Select your printer model and follow the instructions to download and install the latest firmware.
Check Printer Connection
- If using Wi-Fi, ensure the printer is connected to the correct network.
- If using USB, try a different port or cable.
- On your PC, go to Settings > Devices > Printers & Scanners, select your printer, and ensure it's set as default and not paused or offline.
I hope the information shared has been useful and resolves your concern.
Wishing you a smooth and hassle-free experience ahead!
