SUMMARY: Virtual Postscript Fonts or New 600 Printer

This is a summary of the helpful replies on how to modify `dvips &  
mf' to automatically generate the proper TeX fonts for a printer with

a resolution that is not in the default list.

There are four differnt steps that have to be accomplished.

The steps are all described in documents in the dvips and mf

distributions but putting the pieces together took a few
tries so I thought that I would summarize them for the group.

You will need root privileges to change the system files.

1) First you have to add a printer description to Metafont.

On NeXT you have them in a file /usr/lib/mf/inputs/

Values for your printer you may find in a file, which
you will find on CTAN. Get from there also
'metafont-for-beginners' writeup which goes through details of
a process of "dumping" new bases and installing them.  

Note: the mode file ( that I found in CTAN had a
format that was different from the one on my system.  I put
the parameters from the CTAN file into my format.  The
resulting entry in /usr/lib/mf/inputs/ is:

mode_def ljfour =           % 600dpi HP LaserJet 4
 proofing:=0;      % no, we're not making proofs
 fontmaking:=1;      % yes, we are making a font
 tracingtitles:=0;    % no, don't show titles in the log
 pixels_per_inch:=600;      %  obtained from CTAN

 blacker:=.25;              %  OLD style -- don't use mode_param
laserjetfour := ljfour;

2) The new `modes' must be used to create a plain.base file
for mf.  The description for this process is in the dvips
INSTALLATION file: "To make a proper plain.base, assuming the
local mode definitions are contained in (on the NeXT,; on the Amiga,, type the following command
(assuming csh under UNIX):  

localhost> inimf "plain; input local; dump"

(I used the file, of course.)  Now, copy the plain.base file  
from the current directory to where  the base files are stored on  
your system."  

3) plain.base has to be moved (or copied) to the directory

/usr/lib/mf/bases and as indicated in the 'metafont-for-beginners'  
writeup mentioned above: "watch out during updates!
If {\tt mf.base} is a {\em hard link\/}
to {\tt plain.base}, then replacing {\tt plain.base} with its
new version severs the link:  {\tt mf} will still load {\tt mf.base},
but it will be the old version!  The proper procedure is to remove
the old {\tt mf.base}, and relink.  On {\sc unix}:
    rm mf.base
    ln plain.base mf.base
On most {\sc unix\/} systems, {\tt ln -f} will automatically remove
the second file (if present) --- in this case, mf.base --- before  
linking."  (Not mine, the link was cut and the old mf.base was  
sitting there.)

4) Assuming that you called the new mode something like 'ljfour'  
(note that I also made the alias laserjetfour := ljfour;) now you

need to edit the MakeTeXPK script to include the following lines

inside the if/elseif construction:

   elif test $BDPI = 600

Note that you should change the script in the /usr/bin directory

or where ever you system has its executables.

5) Try it.  I used the test.tex file from the dvips source  
distribution.  This is a nice, single-page, robust test of dvips and

forces the automatic font generation ...  dvips -D600 test

Good luck and thanks,

1. Colour postscript on a Canon BJC-600 printer


Can someone kindly tell me a way to print out, on a Canon BJC-600
bubble jet printer, the beautiful colour slides produced with
seminar.sty etc. using a PC (either in Windows or DOS)?

Presumably one needs a colour postscript driver. However, ghostscript
can only do black and white on Canon (and Espon?) printers. Are there
other "drivers"?
