   • If there is a connection problem, follow the instructions in HP Print and Scan Doctor.

Thank you Sandy,

The printer is still fickle and goes offline without any apparent reason.  When it does go offline it is very difficult to get back printing again, even with the suggestions you have kindly made.

It is working fine today, but I don't know why? 

My problem is I expect it will let me down again.  Could it be a firewall/Windows Defender issue??

Kind regards

Steve

Disable the firewall and check if that helps.
