  Here  is  the  way  to  send HPGL command files to a plotter (serial
  port) from an IBM PC/clone:  

  1.  At  the  DOS  prompt, type MODE LPT1=COM1 . This redirects print
  commands to the serial port named COM1.  

  2. At the DOS prompt, type MODE COM1:96,n,8,1,p . This  sets  serial
  communications  to  9600 baud, no parity, 8 data bits, one stop bit,
  with handshaking.  The handshaking is  important  for  large  files.
  Most  HP  plotters have extremely limited buffer sizes, and the data
  can get lost otherwise.  

  3. At the DOS prompt, type PRINT  <filename>.  This  tells  the  DOS
  print command to send the file to your plotter.  

       EXAMPLE:  C:>print hpgl.txt 

  4.  To  re-enable  the  LPT1 (Centronics) port, you must reboot your
  computer.  DOS has not foreseen the need  to  switch  PRINT  outputs
  back and forth between serial and parallel ports.
