Hi Anderson
Yes that HP Z series printer is a challenge to say the least.
However there is one man on here that does know itr inside out.
His name is Ernst; a very nice person that I am sure can help you.
Easiest way to get hold of him would be via email or a personal on line message through the forum.
Therefore Click on this link to his most recent post. It will offer his email address and a link to write a personal message if you prefer.
Have patience though. Hem might take a day or so to see your message.
