Hi! @foxy7385, Welcome to HP forums.

I understand the power light on the printer keeps blinking.

Don't worry I'll try to help you out.

Did you make any changes to your printer?

Have you tried checking with a different ink cartridge?

As you mentioned the power light on the printer keeps blinking and you are getting printer offline error on your PC.

I appriciate your efforts for trying out the steps before reaching out to us.

Please try the steps recommended below.

Remove and reinsert the cartridges

One or both of the cartridges might not have full electrical contact with the carriage. Follow these steps to remove and reinsert the cartridges.

1. Press the Power button () to turn on the product.

2. Open the top cover. The carriage might move to the access area. Wait until the carriage is idle and silent before proceeding.

3. Press down on the cartridge to release it, and then pull it toward you to remove it from the slot.

4. Inspect the cartridge. Make sure that no protective tape remains on the contacts or the nozzles.

5. Hold the cartridge so that the nozzles face down and the contacts face toward the carriage.

     caution:

   Do not touch the copper-colored contacts or the ink nozzles. Touching these parts can result in clogs, ink failure, and bad electrical connections.

6. Slide the cartridge at a slight upward angle into its slot, and then gently push it forward until it snaps into place.

7. Repeat these steps to remove and reinsert the other cartridge.

8. Close the top cover.
