In Metafont the mode definition is used to define dpi and printer specific adjustments on generating the pixelized character images to use for printing.
How could I specify the mode (from a mf file) for a specific printer?
I am using TeX not latex.
I know how to use modes in running mf itself. But how to define the modes.mf file to use and what mode to run while running TeX and letting it autogenerate the fonts.
