If you're using the default template, then it would say something like
at 75x580 prescription 30 60 250x600
which means ... at 75x580 start the prescription text. Use a column width of 30 points, and a maximum of 60 lines. Once you reach the 60 lines in that column, start a new column at 250x600
So, if you increase the font size, you need to increase the width and reduce the number of lines and move the new column point.
