Thermal Sans Mono
Thermal Sans Mono is a set of specialized free bitmap fonts for use on thermal receipt printers and printer emulators.
It is being produced in two sizes.
These are chosen to correspond with hardware bitmap sizes, while the boldness and glyph dimensions are selected for use at around 180DPI.
Thermal Sans Mono is derived from GNU Unifont, and is licensed under the GNU General Public License.
Work in progress
See releases for the most complete BDF and PCF font files currently available.
Many glyphs are not yet available for this font, consider running the build locally and adding definitions for glyphs that you need.
The glyphs are assembled from a variety of methods, with the build process for
each glyph set under
- Tracing a Unifont glyph and then re-drawing it with the specified metrics.
- Scaling a raster
- Generating an image with a script, as in the case of placeholders.
Makefile is produced from the definitions with the
./configure make -j
The dependencies of the build are currently strange and numerous, including font sources, scripting languages, and tracing tools. The entire setup is included in our Travis CI build script.
Add new glyph definitons to the files under
defintions/, and send a pull request. The definitions cover the process to produce each glyph:
- Placeholder: Draw the glyph number.
- Scale: Scale the corresponding glyph from GNU Unifont.
- Trace: Trace and re-draw the corresponding glyph from GNU Unifont.
