Do you want set layout zoom so that the window shows the same info as a previewed window of the same layout or do you want to resize the window itself?
Either way, I'm not sure I see what problem you are trying to solve with this. Keep in mind that the proportions of your monitor aren't the same as your printed page.
Earlier this year you answered a bunch of my questions. Glad to see you're still here.
The users will mostly be running the Kiosk mode on something like a 14" laptop. Even if the Kiosk window on the laptop does not fill the entire screen, my goal is that whatever is on the screen is printed exactly the same way.
I was hoping that there were some standard settings to use to resize the layouts to printed pages. Of course, I could trial and error it if that's the only option.
I don't see any way around layouts customized to the specific page size (US letter or A4) unless the differences are so minor that it doesn't matter.
If you have the desired printer and page orientation options selected in Printer setup, you'll see vertical and possibly horizontal dashed lines on your layout to show the locations of the page breaks. You may be able to use them as a guide to make sure that nothing is to the right of this line to keep the layout matching the printed/previewed page.
Well, it was operator error again. The printer margins were fixed (way off), and I never recalled doing that.
