Thank you for posting on the HP Support Community.
 
I see that you’re experiencing a passkey PIN issue while connecting HP sprocket printer, 
Don’t worry as I’ll be glad to help, however, to provide an accurate resolution, I need a few more details:

When was the last time it worked fine?

Meanwhile, you can try this:
When a list of detected devices appears on the computer display of the BLUETOOTH device, select “HP sprocket printer.” If a passkey* prompted to enter “0000 or 1234"
