Invoice template after update

I’ve noticed that the invoice template that i got when emailed it sends two pages when it should only be one.

How to i fix this its okay when i print the invoice but when its emailed its all over the place.

That’s going to be out of your control, because the versions are generated by different software.

Printing and emailing doesn’t generate PDF the same way. So this could explain the inconsistency. If the invoice is too long, it could go onto second page. Why is this a problem?
