xhtml - What are most useful media="print" specific, cross browser compatible css properties?

Question

What are the most useful media="print"-specific, cross-browser-compatible CSS properties?

I think we have these 5 properties for print specific.

1. page-break-before
2. page-break-after
3. page-break-inside
4. widows
5. orphans

Please explain when and where to use these? Which are cross browser compatible? and what are other common CSS properties can be useful in print, other than display:none?

Answer 1

I use the following:

 /* Browser will TRY to avoid spanning content within across a page */
 tr, td, th {page-break-inside:avoid}

 /* Repeat table headers when table spans a page */
 thead {display:table-header-group}

  /* Apply to anything you don't want to print */
 .NoPrint {visibility:hidden; display:none}
