""" Set of ESC/POS Commands (Constants)
|
|
|
|
This module contains constants that are described in the esc/pos-documentation.
|
|
Since there is no definitive and unified specification for all esc/pos-like printers the constants could later be
|
|
moved to `capabilities` as in `escpos-php by @mike42 <https://github.com/mike42/escpos-php>`_.
