While rummaging the CORE – stylesheet – in 2007 I unconvered an area where there are efforts being made to make pages more print-friendly by hiding some of the un-needed elements. No idea how much of this will exist in the final build.
@media print -
Psst, SharePoint Devs – There is a small glitch with this PRINT implementation (I think) – It seems to have one set of squigly brackets too many.
In any event it looks promising.
