Formtastic cannot move spool data from one page to another. We can only map spool data one page at a time to that form. However, FORMATTER (an optional module for Formtastic) can reformat your data so that when Formtastic gets the spool file, it has already combined the 2 half pages onto one page. With Formatter, you can manipulate how each page prints and incorporate multiple page styles to decrease space used by headers and footers while increasing space dedicated to detail items. This module can potentially reduce a 10 page spool file to 5 pages or less.
