Hardcopy Output with ESPS Plot Programs                        1/22/93 1.11.  Hardcopy from Vector Plot Programs     The ESPS plot programs have a -T option for  specifyingthe type of the output device.   The option "-T hardcopy" isused to to get the default  (for  a  site)  hardcopy.    Thedefault  for the plotting programs is postscript send to thespooler program "lpr".   If this is correct for your instal-lation, then you do not have to do anything else.     The vector plot programs, aplot, genplot, mlplot, plot-field, plotsd, plotspec, and scatplot can plot to a hardcopydevices that  are  compatible  with  Tektronix  plot  codes,Postscript,  or  HP Laser Jet printers.    If the option "-Thardcopy" is used with these programs, Tektronix  compatibleplot  codes  are  sent to a program called esps_plot (in ourbin directory).  This  program  takes  Tektronix  codes  andsends them to a plotter.   By default, this script is set upto convert the plot to Postscript and spool it to  lpr.   Soif  you have a Postscript printer setup so that you spool toit with lpr, then "-T hardcopy" should work  right  off  foryou.     If you have an HP Laser Jet  compatible  printer,  thenuse  the  "-T  hp"  option with these programs.  This optiondoes not spool to the printer, so you must pipe  the  outputto  your  spooler.   For  example:  plotsd  -Thp  file.sd  |print_hp (if print_hp is your HP printer spooler program).     If you have some other type of device, and you know howto  make  it  plot  Tektronix compatible codes, then you canedit $ESPS_BASE/bin/esps_plot to make it handle your device.2.  Hardcopy from Raster Plot Programs     The program for printing spectrograms, plotsgram has  a"-T  hardcopy"  option.  By default this sends Postscript tothe spooler lpr.   To change this  default,  edit  the  file$ESPS_BASE/bin/plotsgram.   You  can make the default one ofPostscript, hp laser jet, or Imagen.    You can also specifythe  name  of  the  spooler program.  It is currently set tolpr.   Search for SPOOL_CMD in the file.
