Hello ardofest,
The only article I could find on the Knowledgebase is this one on banner pages. If this doesn't help, please call Support at 1-800-821-2797.
Our Windows computer with Windows 10 always prints an extra page with the title "Job Messages". Message contains the computer's name, document name, machine's name, page number. We can not disable this page. It is useless, how can we stop the machine print this page?
