The editor for reports and print templates can be found in the Daylite settings under Report Templates.
A technically skilled person can easily adjust things like placement of elements, fonts, colors and images.
However, if you want to make profound changes to the template or if you want to redesign a template from scratch, you should have programming knowledge.
If you have programming skills, the introduction to the concept of the underlying report engine available here will be helpful. If you do not have programming skills, we will be happy to create templates according to your wishes.
