Printing

By default, the content of most elements is included in all output media. The DITA map provides a means to suppress element content from appearing in print-oriented media, or from appearing in non-print-oriented media, such as HTML. The generation or non-generation of print and other forms of output can also be affected through the use of other navigation-related attributes.

The author can specify whether individual topics or groups of topics referenced in a DITA map should be included for processing to print-oriented outputs such as PDF. Each map (or map specialization) and topicref (or topicref specialization) in a DITA map supports the attributes @toc, @processing-role, and @print. The @print attribute supports the following enumerated values, each controlling the way that print-oriented processors handle the inclusion or exclusion of topics or groups of topics.

@print value	Print-oriented Processing	Non-print-oriented Processing
unspecified (default) Example: `<topicref href="foo.dita">`	Topics referenced by the map element are included in output.	Topics referenced by the map element are included in output.
`yes` Example: `<topicref href="foo.dita" print="yes">`	Topics referenced by the map element are included in output.	Topics referenced by the map element are included in output.
`printonly` Example: `<topicref href="foo.dita" print="printonly">`	Topics referenced by the map element are included in output.	Topics referenced by the map element are excluded in output.
`no` Example: `<topicref href="foo.dita" print="no">`	Topics referenced by the map element are excluded in output.	Topics referenced by the map element are included in output.
`-dita-use-conref-target` Example: `<topicref conref="#foo-topic" print="-dita-use-conref-target">`	Topics referenced by the map element derive a value for @print from the @print value of the referenced map element. See Using the -dita-use-conref-target value for more details on this value.	Topics referenced by the map element derive a value for @print from the @print value of the referenced map element. See Using the -dita-use-conref-target value for more details on this value.

Note: If a value for @print is not specified explicitly in a map element, but is specified in a map that references the map element, the @print value cascades to the referenced map. If the @print value is not specified on the referencing map, a default of "yes" is assumed.

Use @print="printonly" to identify transitional topics to be included exclusively in highly contextual or linear print-oriented output.

If the referenced topic should be excluded from all output formats, set the @processing-role attribute to "resource-only" instead of using the @print attribute. Content within that topic may still be referenced for display in other locations.
