Invoice description is not printing bold

Thank you Genreve_S, so the answer is no you cannot bold just headers within the description box. Headers and standard transactions lines are either all bolded or all normal text, whichever format is selected in the customised form. I wonder why then that there is the option to insert a header if it just looks the same as the rest of the text.

Hi jhp, 

When printing or emailing your invoice, the software uses certain forms as a guide for how the invoice will be formatted. So if you want to customize how your invoices look, you will need to edit these invoice forms. Here is a guide that may help you with your task.
