Changing fonts to dot-matrix printer through CUPS

[Eric Wood]

I want to print to a Panasoic dot-matrix printer from the command line.  I 
think I can pass some -o option parameters to set margins, etc.   But what I 
want to do is have it render a slightly larger font.  The printer's built-in 
fonts are too small.

Has anyone done this?  Or does anyone have and printing tip for dot matrix 
printers?
