Hi!

I use centrifuge tubes to store SMD components, an print small labels with 2 or 3 lines. To reach acceptable quality in small prints, i' suggest this things:

  1. Pixel-perfect fonts should be embedded
    • Good start point for search is https://github.com/olikraus/u8g2/wiki/fntlistall
    • May be bdf2ttf can help (but it would be better to find fonts with kerning)
    • Path to embedded fonts should "searcheable" for more compact CLI typing.
    • There are no need to embed hundreds of fonts. Goal is to have at least one useable for each size :)
  2. Add option to define [font + size + line height] implicit.
    • this will allow use embedded pixel-perfect fonts until without "autoselect" algorithm.

Seems hinting info is not used. I see much better results with Roboto font when rendered on node.js via canvas package.

It appeared more simple to create everything from scratch in js. Feel free to reuse any part as you wish.
