The Default invoice template should very closely match the layout all invoices previously shared, with minor changes to the positioning of the company details in relation to the business logo. It is possible to disassociate the logo and the company details and specify that either occupy a position of your choice. To accomplish this, please go to the Style page of the options dialog and check the "Set styles for each text block" radio button, uncheck the "Link Company Logo to this text block" checkbox, and select "Logo" in the text block positioning grid at the desired position.
If you're seeing a dramatic difference between the default invoice template and the old printouts, a bug report would be welcome (and a screenshot of the results you're seeing would be appreciated).
