epcol
Epcol gives access to factory builtin features of ESC-P2 printers
...The macro commands are the macro name, .ep, followed by a command name such as roman (i.e., .ep roman) on a line by itself. The .ep\ proportional command enables the printer builtin proportional spacing font.
The ocfont reviews serve as a question and answer area for epcol and other josephms sourceforge projects and are regularly checked.
Rel_1.2.0 adds support for newer printer fonts (e.g., prestige) with added .ep macros and with command line -style option values.
