If you have the Designer or Pro version, ideally it remembers each design and its last size, so it should only take a few clicks to reprint.
In all versions, you can save the resizing to your computer:
- Enter a size and click the Print button.
- You get the full preview.
- Usually, a window pops up for printing. Close it.
- How to save depends on your computer. There may be a Save command in the File menu or a little disk icon in the toolbar.
