  This package contains four Autotrax v1.61 drivers for HP PCL3 compatible
300 DPI printers. I modified original Laser Jet driver for Autotrax
to speed up printing.
  During printing full A4 page with resolution  300 DPI original driver
have to send about 800KB to printer or file and whole printing takes
a few minutes.
  My driver try to minimize all graphics informations necessary to
create an outplot by choosing the best of HP PCL compression methods 1,2,3
and stripping all unnecessary bytes at the end of each line.

**************************************************************************
*  Compression algorithms are taken from Tony's Parkhurst PCLCM128       *
*  program for compressing PCL graphics files.                           *
**************************************************************************

  I wrote this driver for my HP DeskJet 520 printer and it was tested
on this model. It should work with most HP printers ( see list below ).
  Instalation:
Copy all files to your Autotrax directory, start TRAXPLOT and select
proper HP PCL driver in Setup Printer menu.

           *** This drivers are freely distributable ! ***

  If you find any bugs or have any suggestion, please contact me.
