The following table lists all the attributes in XHTML-Print and notes which are not meaningful,
that is, result in a visible change to the page :
- when printing a static version of the XHTML-Print document,
- because of restrictions of image types to jpeg,
- because only css style sheets are supported, not java style sheets,
- because the the character set of XHTML-Print documents is restricuted to utf-8, and
- because they are part of functionality that is considered too complex for low-cost printers.
The last point is important to us, since we hope that every printer could proved support for
XHTML-print to at least the minimum degree of print quality. The absolute minimum level of print quality
is simply printing the document's text without images.
