bug/doc: Fix invalid EAN-13 barcode in examples
In the various examples and python-escpos CLI there are a number of uses of `13243546557687` as an EAN-13 example. This EAN barcode is invalid as the checksum should be `0` and not `7`. ``` $ python test_print.py Traceback (most recent call last): File "test_print.py", line 5, in <module> p.barcode('13243546557687', 'EAN13', 64, 2, '', '') File "/home/pi/fatt-display/lib/python3.7/site-packages/escpos/escpos.py", line 433, in barcode bc=bc, escpos.exceptions.BarcodeCodeError: No Barcode code was supplied (Barcode '13243546557687' not in a valid format for type 'EAN13') ``` This patch set removes `13243546557687` and replaces it with the valid number `40063813339310`. In researching the list of [assigned prefixes issued by G1][g1-prefixes] there seemed to be no "officially" defined test prefix, so this change was made to be minimally invasive using the number from the existing test cases. Resolves #350 Affects #176 [g1-prefixes]: https://www.gs1.org/standards/id-keys/company-prefix [test-code]: https://www.barcodelookup.com/4006381333931

 python-escpos
 =============

-This library is available over pypi. So for most of the use-cases it should be sufficient to run
+Ensure the library is installed on ${lib_arch}/${python_ver}/site-packages/escpos

-```
-pip install python-escpos --user  # add --pre if you want to install pre-releases
-```
+On CLi you must run:
+# python setup.py build
+# sudo python setup.py install

-For more information please read the documentation at https://python-escpos.readthedocs.io/en/latest/user/installation.html
+On Linux, ensure you belongs to the proper group so you can have access to the printer.
+This can be done, by adding yourself to 'dialout' group, this might require to re-login
+so the changes make effect.
+
+Then, add the following rule to /etc/udev/rules.d/99-escpos.rules
+SUBSYSTEM=="usb", ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="0202", MODE="0664", GROUP="dialout"
+
+and restar udev rules.
+# sudo service udev restart
+
+Enjoy !!!
+And please, don't forget to ALWAYS add Epson.cut() at the end of your printing :)
