You will be asked for confirmation before beginning, so you have a chance to bail out. If you want to continue, type the letter Y, then hit RETURN. If, instead, you want to leave fixhpsp at this point, just hit RETURN.
The plotter spooling will be disabled temporarily. Before restarting the canceled plotter job, fixhpsp will ask you to reset the plotter. Make sure the plotter is powered up, reset, and on-line.

Once the plotter is ready, hit the RETURN key on your terminal. Spooling will then be re-enabled.
