In my script, I'm using Freeze Window before I go to a layout which is my form letter and then printing it. The problem is, the form letter briefly shows on the screen. I thought Freeze Window would hide this layout in my script.

Any ideas?

When you print, it refreshes the screen before it does an acutal print. There is no way around that (That I know at least)

You could, however, instead of freezing the window, create a new window, make it like, 1 x 1 in the top left corner or something, print it, and then close it. I don't see why that wouldn't work.
