Editing Interpress (section)

==Printing Instructions==
This feature set allows the ability to instruct the printer which media to use (paper size, type, color), number of copies, sides printed on as well as finishing actions such as stapling. These instructions are optional and their operation is dependent on the printer capability.

===Example===

{| style="border-spacing: 2px; border: 0px; font-family:monospace; white-space:nowrap;"
|-
| style="width: 320px;" | Header "Interpress/Xerox/3.0 "||  style="width: 210px;" | --standard header--
|-
| {instructions}|| --device instructions--
|-
| BEGIN || --start of master--
|-
| &nbsp; &nbsp;  {preamble} || --preamble--
|-
| &nbsp; &nbsp;  {page 1} || --first page--
|-
| &nbsp; &nbsp;  {page 2} || --second page--
|-
| END || --end of master--
|}

A more complex structure would include Nested Blocks and CONTENTINSTRUCTIONS, a token used to distinguish content-instructions bodies from page bodies. In general, the content instructions are given precedence over the document instructions. Nested Blocks {BEGIN..END} allow for constructing large documents out of smaller ones.
