linemode 0.1.0

Drivers and templates for thermal printers

Basic, without template system:

from linemode import open_printer

printer = open_printer('star+lpt:///dev/usb/lp0')

printer.run_commands([
    ('fontsize-large'),
    ('select-bold'),
    ('write', "Hello world\n"),
    ('cut-through'),
])

Running templates:

from linemode import open_printer
from linemode.renderers import line_mode

printer = open_printer('star+lpt:///dev/usb/lp0')

printer.run_commands(line_mode.render("""
<document>
  <line>
    <bold>Hello world</bold>
  </line>
</document>
"""))

With jinja:

from jinja2 import Template

from linemode import open_printer
from linemode.renderers import line_mode

printer = open_printer('star+lpt:///dev/usb/lp0')

# jinja2 template
template = """
<document>
  {% for potatoes in [1, 2, 3, 4] %}
  <line>
    {{ potatoes }} potato
  </line>
  {% endfor %}
</document>
"""
# line mode printer document
document = Template(template).render()

# iterator of generic printer instructions
commands = line_mode.render(document)

# printer specific compiled representation
program = printer.compile(commands)

printer.execute(program)
