Use of "position absolute" breaks the single-pass nature of XHTML-Print.
Thus an Enhanced Layout printer, as currently defined, needs enough memory
to store all the XML.
This may not be a bad thing, since that printer is probably also powerful
enough to do photo processing. I actually thought this was intentional.

rg Positioning

All:
I would like to formally raise the issue of ABSOLUTE positioning in
CSS-Print.
As it is currently defined, in Print Enhanced mode, an element can be
absolutely positioned using the "position absolute" property/property value
pair. This means that at the bottom of a page, it is quite legal to add a
header which is, of course, behind the current "cursor" position on the
page. (See http://www.w3.org/TR/REC-CSS2/visuren.html#comparison for a
comparison of the various positioning methods allowable in CSS.)
Lexmark's issue with this is not strictly the ability to absolutely
position but rather the problem with moving backwards on the page. It
would be workable to have all the absolutely placed elements at the start
of the page when they can be cached and dealt with as the page is built but
that is not required in CSS. As such we would like to either remove the
ability to do absolute positioning completely or alternatively require that
absolute positioning shall not reference a location on the page "behind"
the current "cursor"position.
I'll add this to the agenda.
