Python 2.7 EOL is arriving on 2020-01-01: https://pythonclock.org/
This will allow us to use Python 3 only libraries, like python-barcode,
which can maintain a reduced, simpler codebase, due to only one version
to support.
Closes#371.

* add a method to check barcode code format
ensure that the code to print is compatible with the ESC/POS formats and
also automatically check this format before printing (barcode() method).
* rewrite test using pytest's parametrize functionality
* add test for the 'check' argument
* update authors list
The DLE EOT command allows querying the status of several features of
the printer.
Added to the online/offline status developed in #237, this commit adds a
paper sensor querying.
Tested with an Epson TM-T20II, which only has an end-paper sensor. The
near-end paper sensor should be tested with a compatible printer.
However, the implementation is quite straight-forward.
* Added the DLE EOT querying command.
Added a function to check whether the printer is online or not, as well
as a reading method for USB printers.
* Update AUTHORS
* Add entry to .mailmap
* currently USB only
