IT WOULD BE HELPFUL TO HAVE CONTROL OVER WHAT GETS PRINTED. ...DATE RANGE; HEADERS, PAPER SIZE

Yes. Best if can print current view. Also good if project can remember specific settings (project profile settings) so that last view settings are used on next start-up.

When printing any significant plan, space is likely at a premium.  The fact that it puts a full week, month etc. (depending on your zoom level) at the beginning of the project is a real pain.  If my project is so long that I need to zoom out to see it, I definitely don't want it to add an extra month between the tasks and the gantt chart
