If anyone else has this issue where the footer of your invoice is all overlapped and unreadable here is a quick fix.
Type in your footer as per normal and place a full stop between the lines.
eg:
Here is some footer text on the first line
.
this would be line two of your footer text
.
this would be line 2 of your footer text
I have found it only seems to happen on longer lines, so the easy way to find out make your footer then email a blank invoice to yourself and see if anything is overlapped. If it is just add the full stop like in my sample above.
This was such a frustrating issue and I got so many complaints from customers they couldn't read my bank details and this was the only way I can find around it so far.
hope others can benifit from this.
