There's a button on the toolbar that looks like a magnifying lens over a window that will automatically resize and recenter the drawing before plotting. This is necessary if your plots are based on zoom. Also, if you print directly without converting to pdf, the lines are annoyingly thick. You can change this by going to tools > options. For the option, type "pen1_line_weight" and set a value of 1.5, and do the same thing for "pen3_line_weight".
Good luck,
