    %	You may do anything you wish with this font definition, as
    %	long as you retain the original copyright notice and credit

    %	for distribution of either the source or any fonts derived
    %	from it beyond a reasonable copying or communications charge.
    %
    % Disclaimer:
    %
    %	While I have made every reasonable effort to make this font
    %	definition correspond to the specifications in ANSI Standard
    %	X3.17-1977, I do not guarantee that it conforms fully to all
    %	official requirements for the OCR-A font, nor that the char-
    %	acters produced from this definition will be usable by any
    %	particular OCR hardware and/or software.  It is the respon-
    %	sibility of the user to determine the usability of this font
    %	definition for his application.  Use of this font definition
    %	is totally at the user's own risk and without any warranty
    %	whatsoever, express or implied.  Neither the author nor his
    %	employer will be responsible for any damages, including
    %	secondary or consequential damages, arising out of the use of
    %	this font definition.
    %
    %	The four ASCII characters "Tilde", "Underline", "Grave Accent",
    %	and "Vertical Bar" do not appear as part of ANSI X3.17-1977.
    %	In order to make a complete ASCII character set, I supplemented
    %	the standard with my own designs for these four characters.
    %	Since these characters are not part of any standard, they will
    %	presumably *NOT* be readable by any existing OCR-A equipment.

Licence terms for Norbert Schwarz' work

https://mirrors.ctan.org/fonts/ocr-b/README ::

    To my knowledge, the original typeface for OCR-B was developed by
    Adrian Frutiger.  In Germany there even exists an industrial
    standard - DIN ????? - that describes the typefaces.  Based on such
    material the input has been developed.  I cannot speak to the legal
    consequences of these.
    
    As far as the digitization in METAFONT input which I have
    developed, you may freely use, modify, and/or distribute any of
    these files or the resulting fonts, without limitation.  A previous
    release of ocr-b only granted rights for non-commercial use; that
    restriction is now lifted.

    They are available for free use, including in commercial applications;
    my own contributions are public domain, and others have licensed their
    copyright claims.

https://tsukurimashou.org/ocr.pdf ::

    I make no copyright claim on these fonts myself. I do not believe
    anyone else makes a copyright claim that would conflict with the use of
    these fonts in a commercial project, but I cannot speak for any party
    other than myself.
