Python library to manipulate ESC/POS Printers.
------------------------------------------------------------------
1. Dependencies
In order to start getting access to your printer, you must ensure
you have previously installed the following python modules:
* pyusb (python-usb)
* PIL (Python Image Library)

Python ESC/POS is a library which lets the user have access to all
those printers handled by ESC/POS commands, as defined by Epson,

3. 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:
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
lsusb -vvv -d xxxx:xxxx | grep bEndpointAddress | grep 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 "0x82", if you have other values then you can define
with your instance.

4. Define your instance
The following example shows how to initialize the Epson TM-TI88IV
*** NOTE: Always finish the sequence with Epson.cut() otherwise
you will endup with weird chars being printed.
from escpos import *
""" Seiko Epson Corp. Receipt Printer M129 Definitions (EPSON TM-T88IV) """
Epson = escpos.Escpos(0x04b8,0x0202)
Epson.text("Hello World")
Epson.image("logo.gif")

There are some different prints I'd like to acquire, but unfortunately
not all, even used, are cheaper and easy to get.
