A2 card stock 4.25 x 5.5 I want to use for invitations

[pattypat4495]

I have A2 card stock and want to print invitation on it but my printer doesn't show the correct size picture I need printed. It is either off center or cut off. Can anyone help please?

From what I can see, your printer does not support "A2 card stock 4.25 x 5.5". I highly recommend using a supported paper size.
 
You can certainly configure a custom-size in Windows, however, there is no guarantee that it will work.
