Sending control strings to HP DesignJet 430

Hi all,

I am new to Microstation, trying to learn as I go.  I need to force a form feed on the HP plotter after it has finished drawing my plot.  Left unattended, it will eventually eject the finished plot but if there are several plots to be done, it will speed up my job to send some control string/code to the plotter to eject the last plot and start the next one in the queue.

I did some research on the internet looking for DesignJet 430 control codes and also some research on the plot driver for Microstation or Windows, whichever is the one accessible from within V8 2004.  I found one plot driver which had "end_plot=eject" listed after the pen styles and thought that might do the trick but my friend tried it (I dont have a plotter here at home and he does) and it didnt work.

Anyone done this before or know how to do it?  As I said, I am new so please be plentiful with any comments, dont assume I know some of the inside tricks to accomplishing these type manipulations.

Thanks,

Jerry
