Obtaining hardcopy

On Starlink print the file on the queue associated with the Zeta plotter. If the Plotter is attached to a terminal line, then TYPEing the file at the terminal will produce a plot. On Starlink:

$ PRINT/NOFEED/QUE=ZETA PGPLOT.ZET

To stop a Zeta plot job, once it has been started, use the buttons on the plotter. Press PAUSE, NEXT PLOT and CLEAR. Only after this sequence is it safe to delete the job from the ZETA Queue. Failing to press the NEXT PLOT button will not correctly advance the paper. Failing to press CLEAR but, deleteing the current job can prevent the following plot from being plotted.
