Method, system, and computer code for preparing markup language documents containing multi-line text elements for WYSIWYG printing. The document is rendered in a prepress server system by a duplicate of the browser that was used to prepare the document in the client system. User-imposed line breaks are identified by reviewing text elements for break characters. Browser-imposed line breaks are identified by comparing spatial location information from the browser for each sequential pair of characters in a text element. The collective line break information is used to ensure that the line breaks viewed by the user are maintained when the document is converted to a prepress system.
