Printer error message - unknown system error

My HP890C has worked fine for years. A while ago I ran
disk cleanup and ever since then have not been able to print.

When I click on "print" I can hear the computer trying to
read the "A" drive. Then I get the error message " There
was an error writing to LPT1 due to an unknown system error.

I don't know if this is related but I can no longer play
Solitaire (get "illegal" error message) and the computer
also tries to read the "A" drive when I shut down the
computer.

Has anyone had any experience with this and successfully
resolved the problem?
Thank you.
