The MediaWiki CSS file commonPrint.css (skins/common/commonPrint.css) contains the following CSS rule (lines #161-164):

p, .documentDescription {
    margin: 1em 0 !important;
    line-height: 1.2em;
}

The !important specifier should be removed. It sets paragraph margins to 1em, regardless of the actual styling and layout of the page (in regular mode). Many pages in the Hebrew wikisource make use of special styling/layout of the text, and this rule breaks the style in print mode, makes them effectively unprintable.
Major wikis (i.e., http://en.wikipedia.org/wiki/MediaWiki:Common.js) try to avoid this problem by providing some overloaded rules --
   mw.util.addCSS( '@media print { sup, sub, p, .documentDescription { line-height: normal; }}');
However, due to the !important specifier, subsequent rules cannot alter the original one.
