What font is supported for printing?

Precisions

The flows of dematerialization are sometimes broken, and require the production of writing on paper. The user in some cases may also be more comfortable using printed documents rather than 100% electronic. Prints have a significant environmental footprint, whether in the consumption of paper, consumables such as cartridges and printing inks. The presentation needs in electronics or in printing are different. On the other hand, limiting the environmental footprint should lead to a reduction in the density and volume of information printed.

Use Case
