Print PDF of contribution receipts is putting content to close to margins, and the right hand is flowing outside the page

ref http://forum.civicrm.org/index.php/topic,16563.msg70744.html#msg70744

while this can be slightly controlled by change 'width' in systems msg tpl to smaller than 600 so the pdf renders all content on screen - when printed it loses some on left hand side always, and on right if width is over 600.
