I continually get the Printer blocked "Ocean" unknown certificate error when trying to print from my android phone to my HP printer. It used to work and suddenly started displaying this error. Please help, so frustrated!!

Don't worry as I'll be glad to help, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• Could you please share the picture of the error message? 
• Are you able to print from other devices? 
• What is the product number of your device? Use this link to find it: http://support.hp.com/us-en/document/c03754824

Hi, thanks for trying to help me! I'm not sure if there was a software update.

Here is the error message - it no longer says "Ocean" error. 

Yes I can print from my desktop. The device I'm trying to print from is my phone, a Samsung S20 FE 5G, model # G781W. 

Thanks!!

Thank you for posting back.
 

Let's uninstall HP smart app and drivers first:
Open the Google Play Store, tap the Menu icon , and then select My apps & games. Select the HP Smart app, and then tap Uninstall.

Once it's done, try and install HP smart app and print service plugins from here: https://support.hp.com/us-en/document/ish_1870466-1870510-16
 

Hope this helps! Keep me posted for further assistance.
