An example is better than thousands words:
from PIL import Image
from ThermalPrinter import *
with ThermalPrinter(port="/dev/ttyAMA0") as printer:
# Picture
printer.image(Image.open("gnu.png"))
# Bar codes
printer.barcode_height(80)
printer.barcode_position(BarCodePosition.BELOW)
printer.barcode_width(3)
printer.barcode("012345678901", BarCode.EAN13)
# Styles
printer.out("Bold", bold=True)
printer.out("Double height", double_height=True)
printer.out("Double width", double_width=True)
printer.out("Inverse", inverse=True)
printer.out("Rotate 90°", rotate=True, codepage=CodePage.ISO_8859_1)
printer.out("Strike", strike=True)
printer.out("Underline", underline=1)
printer.out("Upside down", upside_down=True)
# Chinese (almost all alphabets exist)
printer.out("现代汉语通用字表", chinese=True,
chinese_format=Chinese.UTF_8)
# Greek (excepted the ΐ character)
printer.out("Στην υγειά μας!", codepage=CodePage.CP737)
# Other characters
printer.out(b"Cards \xe8 \xe9 \xea \xeb", codepage=CodePage.CP932)
# Accents
printer.out("Voilà !", justify="C", strike=True,
underline=2, codepage=CodePage.ISO_8859_1)
# Line feeds
printer.feed(2)

So the module can be used as simply as:
with ThermalPrinter() as printer:
# ...
Or:
printer = ThermalPrinter()
