I haven't been able to figure this out, or find any resource for this.
I'd like to be able to know, in javascript, if the media that's rendering
is screen or print. I have no nefarious purpose here (I've often seen
people wanting to do this to prevent printing): I have a report that uses
javascript to page 20 items at a time and I want it to show all items at a
time when printing.
- I can make it more or less work on IE using onbeforeprint, but no luck
on better browsers
- When the page first renders the combination of @print and @screen styles
work good, but the moment javascript hides stuff it stays hidden (because
it's changing the element.style attribute of the rows.
- I've tried figuring it out by having an element with different styles
declared in the @print and @screen rules of the stylesheet, but I can't
make it show any difference to the javascript being executed (e.g.
changing the position of this element for print and screen, the element's
position is always what is first calculated for the screen).
Any other ideas?

So you want to create a print media only style sheet (and !important )?
<snip> ... the moment javascript hides stuff it stays hidden ... .
Hence the !important in the print style sheet.
<snip> ... element's position is always what is first calculated for the screen).
Yes, it is unlikely that a print renderer would be executing javascript,
they don't need to be interactive.
Richard.
Just disable js for that page alone and only for printing, when done,
enable it right back.
