The DocBook xslTNG Stylesheets anticipate that “print” output, that is, paged media, will be provided with a CSS formatter such as AntennaHouse or Prince.

The stylesheet intended for paged media output produces slightly different HTML than the online stylesheet. This print customization assures that JavaScript features are disabled and changes the markup used for some elements.

The resulting “.pdf.html” file is then processed by the formatter.

In as much as the different CSS formatters behave differently and have different extensions for features that are needed in print but not yet standardized, additional customization may be necessary.
