"""A simple command-line interface for common python-escpos functionality
|
||||||
|
|
||||||
|
Usage: python -m escpos.cli --help
|
||||||
|
|
||||||
|
Dependencies:
|
||||||
|
- DavisGoglin/python-escpos or better
|
||||||
|
- A file named weather.png (for the 'test' subcommand)
|
||||||
|
|
||||||
|
Reasons for using the DavisGoglin/python-escpos fork:
|
||||||
|
- image() accepts a PIL.Image object rather than requiring me to choose
|
||||||
|
between writing a temporary file to disk or calling a "private" method.
|
||||||
|
- fullimage() allows me to print images of arbitrary length using slicing.
|
||||||
|
|
||||||
|
How to print unsupported barcodes:
|
||||||
|
barcode -b 'BARCODE' -e 'code39' -E | convert -density 200% eps:- code.png
|
||||||
|
python test_escpos.py --images code.png
