Dear Anam,
Many thanks for your email and steps to resolve the problems that I've been
having.
I have to say that I had doubts that I would ever be able to use the HP
printer again with Linux.
I had spent many many hours trying to resolve the issue before receiving
your email without success.
So it is with great delight that I followed your instructions and have just
managed to print a pdf document and am very happy!

Thank so much for your help.

Regards,
Ciaran Mulloy
