1 HARDCOPY
  Syntax: HARDCOPY [device]

  The  first time  you ask for  a  hardcopy you will  be  prompted for the
  hardcopy  device  you want.  All  subsequent plots  will go  to the same
  device,  unless you say  `HARD  new_device'. If you give  the `HARDCOPY'
  command  in a macro  and omit  the  device name  the first  time, device
  `METAFILE' will  be selected. To  print the plots you  have already made
  issue the  command  `CLOSE'. You  can then  print the file  from another
  session, or use the `SPAWN' or `SHELL' commands. Use the
  `SET HARDCOPY' command to change the filename.

  Note that what `HARDCOPY' actually does is to repeat the plotting
  commands that were used to make the picture. Thus if you change a
  histogram, by fetching in a new one with the same identifier or
  performing some operation on it after that histogram has been
  plotted, the new histogram will get drawn when you give the `HARDCOPY'
  command. Another, sometimes unexpected, side-effect is that if you
  are windowing and project an Ntuple several times with the same
  secondary identifier each time, but different cuts, the `HARDCOPY'
  command will plot the last histogram only for all the projections.
  If your hardcopy comes out differently from the picture on the
  screen this is probably the reason. Try the `REDRAW' command before
  `HARDCOPY' to see what the hardcopy will actually look like.

  Different hardcopy devices are supported for different graphics
  packages.  See HELP Hardcopy_Devices for more details. If you want
  to use a device other than those listed, you must give its number
  (see GKS or PLTSUB manuals). It will be captured as device type
  `unknown' and the output file will be `plot.dat' unless you have
  specified otherwise.
