This was tested on ZJ-5890 with success. By default centering is deactivated for backward compatibility. Trying to center a QR code in native mode will raise an exception as we do not know ATM if the native rendering is centered by default or not. * Added basic tests for center feature * Check image size before centering

Description
-----------
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, from a Python application.
The library tries to implement the functions provided by the ESC/POS-commandset and supports sending text, images,
barcodes and qr-codes to the printer.
Text can be aligned/justified and fonts can be changed by size, type and weight.
Also, this module handles some hardware functionalities like cutting paper, control characters, printer reset
and similar functions.
Since supported commands differ from printer to printer the software tries to automatically apply the right
settings for the printer that you set. These settings are handled by
`escpos-printer-db <https://github.com/receipt-print-hq/escpos-printer-db>`_ which is also used in
`escpos-php <https://github.com/mike42/escpos-php>`_.
Dependencies
------------
This library makes use of:
* `pyusb <https://github.com/walac/pyusb>`_ for USB-printers
* `Pillow <https://github.com/python-pillow/Pillow>`_ for image printing
* `qrcode <https://github.com/lincolnloop/python-qrcode>`_ for the generation of QR-codes
* `pyserial <https://github.com/pyserial/pyserial>`_ for serial printers
* `viivakoodi <https://github.com/kxepal/viivakoodi>`_ for the generation of barcodes
Documentation and Usage
-----------------------
The basic usage is:
.. code:: python
from escpos.printer import Usb
""" Seiko Epson Corp. Receipt Printer (EPSON TM-T88III) """
p = Usb(0x04b8, 0x0202, 0, profile="TM-T88III")
p.text("Hello World\n")
p.image("logo.gif")
p.barcode('1324354657687', 'EAN13', 64, 2, '', '')
p.cut()
