Printing OpenOffice.org Writer Files

Last Saturday, I printed about a week's worth of work of course materials. I observed that I have some undesirable rendering in my Math elements like radical signs and brackets in the printed copies. It is probably the font and font attributes from one computer to another as I used a different workstation for printing from where I did my encoding. Not portable eh? I will try using the save to PDF feature of OpenOffice.org more in the future, and print the PDF files instead.
