A PostScript(tm) Type 1 MICR Font released under the GPL.

This font is released under the GNU General Public License ("GPL")
|
|
(see the file COPYING for details).
|
|
|
|
Important details to note about the license:
|
|
|
|
1) This font comes with NO WARRANTY. I am not responsible for any
|
|
damages or expenses resulting from its use.
|
|
|
|
2) This font may only be distributed with the license and the source code
|
|
to the font intact. It's not exactly clear to me how the GNU GPL applies to
|
|
fonts, but in my eyes, the font file "GnuMICR.raw" is the "source code" to
|
|
this font, and the files "GnuMICR.pfa" and "GnuMICR.pfb" are the compiled
|
|
versions. if you redistribute the "compiled" version, you must also
|
|
distribute, or offer to distribute, the "source" version (see COPYING).
|
|
|
|
Also, it is my wish that this font not be distributed in such a way
|
|
that it is built into a proprietary piece of software. I'll leave
|
|
the legal wrangling to the lawyers, but in my opinion, if you
|
|
write, say, a non-GPL'd check printing application for Windows,
|
|
you should not hard-code or embed this font into your application.
|
|
I feel that this would be the font-equivalent of linking libraries.
|
|
If you wish to distribute this font with your app, that's fine,
|
|
but I feel that it should be distributed alongside the application,
|
|
with all copyright & license info intact, per the terms of the GPL.
|
|
|
|
I have spent MANY hours on this font. Please respect my work, and
|
|
follow my wishes regarding licensing of this particular font.

|
|
Ok, with that out of the way...
|
|
|
|
A while ago, I set out to be able to print my own checks under Linux. The
|
|
first requirement was that I find a MICR font (those funky numbers and
|
|
symbols at the bottom of your check) that could be freely
|
|
distributed with the application. I quickly found that such a thing didn't
|
|
exist, so I set out to make my own. This font is the result.
|
|
|
|
I coded this font by hand, without the aid of any GUI font application.
|
|
My goal was to be as accurate as possible, with complete control over
|
|
the resulting font. I found dimensions and other specs for the font
|
|
and their use at http://www.cdnpay.ca/eng/rules/006.ENG.htm
|
|
This seems to be mostly geared towards Canadian standards, but the MICR
|
|
font is an ISO standard, and the glyph dimensions should be the same
|
|
as are used in the United States.
|
|
|
|
My sole source for information for this font was the URL above. This font
|
|
is NOT a modified version of any existing MICR font.
|
|
|
|
The "source code" to this font is the file "GnuMICR.raw" This file
|
|
may be converted into an actual Type 1 (.pfa or .pfb) font with
|
|
the "t1utils" package available
|
|
at http://www.lcdf.org/~eddietwo/type/#t1utils
|
|
|
|
I have not had this font tested by any bank. You should get best results
|
|
with a 600dpi PostScript(tm) printer, probably worse results with a 300
|
|
dpi laserjet printer via GhostScript. The hinting on the font is likely
|
|
not perfect, so rendering at lower DPI may introduce some errors.
|
|
|
|
I have had some very good reports of people using this font for
|
|
commercial printing, however.
|
|
|
|
I'm not a PostScript(tm) expert by any means. If anyone who is reading
|
|
this document _is_ and would like to offer suggestions or patches for the
|
|
font or its associated .afm file, please feel free to do so.
|
|
|
|
Also, if you have access to the tools needed to really test the font,
|
|
and you feel like doing that, I would really like to hear from you.
|
|
I'd like to make this the best MICR font available. I think it's
|
|
well on its way - see "comparison.png" for an overlay of GnuMICR
|
|
vs. a sample from a commercial font. Note the strange arcs in some
|
|
regions of the commercial font.
|
|
|
|
The TTF font provided in this package was converted by a third
|
|
party using Windows NT. As such, I have very little confidence
|
|
in the quality of the TTF font. If you want the result of my hard
|
|
work on dimensional accuracy, use the postscript font.
|
|
|
|
See the file INSTALL for help installing this font.
