The blank lines on a legal Petition form I'm preparing (bought/downloaded online from uslegalforms.com) will not print out blank. It looks very normal, but the preview and printout itself filled the blanks with {FORMTEXT} or {FORMCHECKBOX}.

Could there be some hidden code, like the code that also prints when your document has blue hyperlinks (unless I click "Remove Hyperlink" very laboriously one by one? Can anyone help me?
