Hi,
Here is some AS2 code that I wrote to do this - the _toPrint is a
MovieClip containing lots of stuff with filters on. There is scaling
too - depending on whether the user has chosen portrait or landscape -
for later AS3 code, I worked out the orientation and rotated the printed
image - not bitmapped though...
The whole lot is rendered to a Bitmap, then printed.
Hope this helps. I may even get round to blogging it one day :)

Hi Jim,
Yeah we tried the printAsBitmap option, but it didn't make much of a
difference. We're now looking at creating a BitmapData and printing
that. Maybe that works.

Hi there,
We use filters (shadows and glows) to make the scene look better. At
some point a user can print what they've created, but the print
shows no filters. Is there an easy way to get the filters on the print?
Have you tried printAsBitmap? I found that was the only way to get
some stuff to print the same way it was displayed, even when filters
weren't involved (like some hand-drawn shadows using transparent fills).
My project was written in AS2; I don't know whether the implications
are different for code running in AVM2.
