Can I export the check layout attributes or somehow back them up to have
different size templates for different sized envelopes?

You set up your first account as a template. Then you can use the duplicate function to duplicate the current account to add a new account.
- You can click ezCheckPrinting top menu "Account", then click the sub menu "Duplicate Current Account".
- Then click the top menu "Accounts", and click the sub menu "Select Account" to view account list.

ezCheckPrinting does not support layout export feature. I will forward add this request to our TODO list.

Thank you for your suggestion.
