Question

I have a silverlight control that prints to about 1.5 pages. I’d like to try and scale to fit onto a single page.

I’m using the new Printing API in Silverlight 4.

I’ve modified the docToPrint.PrintPage handler as follows :

    var renderHeight = item.RenderSize.Height;
    var printableHeight = args.PrintableArea.Height;

    var scale = printableHeight / renderHeight;

    item.RenderTransform = new ScaleTransform()
    {
        ScaleX = Math.Min(1, scale),    // dont zoom in
        ScaleY = Math.Min(1, scale)
    };

    item.UpdateLayout();
    args.PageVisual = item;

This just calculates the transform needed to fit to page. In fact the on-screen rendered control shrinks accordingly – but it always prints out full size.

I know Shawn Wildermuth blogged about printing – and some of the comments at least suggest that transforms don’t work for printing.

Is there a workaround for this yet? To be frank I don’t actually need printing support – but was just adding it as a bonus feature – so I’ll just have to split the page at an arbitrary point if i can’t figure this out.
