HP LJ 4000 MF modes

[Nicolai Langfeldt <janl@math.uio.no>]

Hi,

I have made a mf mode for the HP LJ4000 in 'FastRes 600' mode.  The
printers default 16ppm 600dpi mode.  There is already a ljfzzz mode
for the same printer in ProRes 1200 mode (more about that later).
With this mode the T1 based output and the PK based output looks
identical to me.  It's a bit spindly for my tastes, but probably
Correct, if the T1 fonts can be trusted.  ... My copy of the TeXbook
appears to have slightly heavier print.  But my copy of TACOP has as
light print as the T1 fonts and this mode gives.

mode_def ljfzzzfr =                     %\[ HP LaserJet 4000 FastRes 600
  mode_param (pixels_per_inch, 600);
  mode_param (blacker, 0);
  mode_param (fillin, .2);
  mode_param (o_correction, 1);
  mode_common_setup_;
enddef;

I have also been looking at the ljfzzz mode with the printer in ProRes
mode.  The print is heavier than the T1 fonts (in ProRes or FastRes mode).
Its print is comparable to PK fonts made with ljfivemp mode prited on
the hp4000 though.

With this mode, i get PK fonts that prints as light as the T1 fonts:

mode_def ljfzzz =
  mode_param (pixels_per_inch, 1200);
  mode_param (blacker, 0);
  mode_param (fillin, .2);
  mode_param (o_correction, 1);
  mode_common_setup_;
enddef;

Actually, I'm totaly clueless about mf.  The above was made using the
guidelines in modes.mf and no prior experience.
