While I agree that the developer should not have direct access to the printer (as in being able to initiate a print), I like where IE is headed (hopefully) in letting the developer specify page-breaks and page formatting.
I think it would be just grand if when you specified a <thead> and a <tfoot> that they would be printed as such, and it would let you say 'print landscape, with no margins'.
Working in an environment where reports are generated for everything and anything that they can find numbers for, being able to control print formatting would make the web that much more valuable.
