Now it would be great if she could actually use the program to produce her school projects.
How is the border stopping her from doing her work?
I am a student using AC10 as well, and it never has prohibited me from doing work.
A decent work around.......say you are printing a 24x36 sheet. Make the layout for a few inches larger and put a single line (vert and horz) to define every corner. Print on a larger sheet, and trim the paper to 24x36.
Are you getting a total border, when I print, I only get a logo in the upper right corner, the older versions used to have the border, my newer version is much less intrusive.
But to answer the original question, no you can not turn it off. It is part of the educational package, so you don't use it for commercial use.
