Define your printer¶(source: http://code.google.com/p/python-escpos/wiki/Usage)

Define your printer

Before start create your Python ESC/POS printer instance, you must see at your system for the printer parameters. This is done with the 'lsusb' command.

First run the command to look for the "Vendor ID" and "Product ID", then write down the values, these values are displayed just before the name of the device with the following format:

xxxx:xxxx

Example:

# lsusb
Bus 002 Device 001: ID 1a2b:1a2b Device name

Write down the the values in question, then issue the following command so you can get the "Interface" number and "End Point"

# lsusb -vvv -d xxxx:xxxx | grep iInterface
    iInterface              0
# lsusb -vvv -d xxxx:xxxx | grep bEndpointAddress | grep OUT
      bEndpointAddress     0x01  EP 1 OUT

The first command will yields the "Interface" number that must be handy to have and the second yields the "Output Endpoint" address.

By default the "Interface" number is "0" and the "Output Endpoint" address is "0x01", if you have other values then you can define with your instance.

Define your instance¶

The following example demonstrate how to initialize the Epson TM-TI88IV

from escpos import *
""" Seiko Epson Corp. Receipt Printer M129 Definitions (EPSON TM-T88IV) """
Epson = escpos.Escpos(0x04b8,0x0202,0)
# Print text
Epson.text("Hello World")
# Print image
Epson.image("logo.gif")
# Print barcode
Epson.barcode('1324354657687','EAN13',64,2,'','')
# Cut paper
Epson.cut()
