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 fixprsp at this point, just hit RETURN.
The printer spooling will be disabled temporarily. Before restarting the canceled printer job, fixprsp will ask you to reset the printer. Make sure the printer is powered up, reset, and on-line. Once the printer is ready, hit the RETURN key on your terminal. Spooling will then be re-enabled.
