WPF Printing – why is it small

Mark Shurmer Profile: MarkWPF

When you get to printing in WPF, you will find it so much easier than printing in previous Microsoft UI design (ie Winforms and MFC). See a previous post of mine to see how easy.

One thing that does occur though, is that when you print your element/canvas/grid/whatever, it will usually go on the printer very small. Why is that?
Actually, I think it is a good thing 🙂
What it means is that it’s printing exactly the same on the printer as on the screen, something we have been begging for, for ages [well since we’ve had GUI’s anyway].

So how can you make it bigger, well it’s pretty easy when you know how:

You simply make the element bigger by using a Transform before printing, like

grid.LayoutTransform = new ScaleTransform(6,6);
printDlg.PrintVisual(grid, “My vision”);
