        A Python support for Epson |copy| ESC/POS |reg| compatible printers. Read more
        at `Epson ESCPOS FAQ`_ (PDF document).
        
        This project is inspired on Manuel F. Martinez work for `python-escpos`_
        implementation, among other projects, whose specific bits of work (available
        here on Github and many other open-source repositories) has helped so much.
        
        The ESC/POS |reg| is a standard that every manufacturer tend to modify to suit
        their (even already implemented) needs. Indeed, there is no standard but
        something awkward, an illusion of a standard. On the surface, one can say
        that it's pretty much the same, but when you look just a little bit more deeper,
        you quickly realize that they are almost completely different, even between
        models belonging to the same manufacturer.
        
        This project aims to make viable the use, at the *point-of-sale* (POS), of
        different printers (the most common ones, at least) that are minimally based on
        ESC/POS |reg| standard, without need to modify the client application code. To
        achieve this, it is necessary to draw a lowest common denominator between
        features and provide implementations that seek to meet this minimum.

        You can get a list of all available implementations with the following snippet:
        
        .. sourcecode:: python
        
            from escpos import helpers
        
            for impl in helpers.find_implementations(sort_by='model.name'):
                print('{:.<25} {}'.format(impl.model.name, impl.fqname))
        
        Which produces an output similar to::
        
            Bematech MP-4200 TH...... escpos.impl.bematech.MP4200TH
            CB55-C................... escpos.impl.unknown.CB55C
            Daruma DR700............. escpos.impl.daruma.DR700
            Elgin I7................. escpos.impl.elgin.ElginI7
            Elgin I9................. escpos.impl.elgin.ElginI9
            Epson TM-T20............. escpos.impl.epson.TMT20
            Generic Daruma........... escpos.impl.daruma.DarumaGeneric
            Generic ESC/POS.......... escpos.impl.epson.GenericESCPOS
            Generic Elgin............ escpos.impl.elgin.ElginGeneric
            Nitere NPDV-1020......... escpos.impl.nitere.NitereNPDV1020
        
        
        Usage Examples
        ==============
        
        Serial RS232 Example
        --------------------
        
        Serial communications support requires `PySerial`_ version 2.7 or later.
        
        .. sourcecode:: python
        
            from escpos.serial import SerialConnection
            from escpos.impl.epson import GenericESCPOS
        
            # assumes RTS/CTS for 'ttyS5' and infers an instance of RTSCTSConnection
            conn = SerialConnection.create('/dev/ttyS5:9600,8,1,N')
            printer = GenericESCPOS(conn)
            printer.init()
            printer.text('Hello World!')
        
        
        Network TCP/IP Example
        ----------------------
        
        You can connect to your printer through network TCP/IP interface.
        
        .. sourcecode:: python
        
            from escpos.network import NetworkConnection
            from escpos.impl.epson import GenericESCPOS
        
            conn = NetworkConnection.create('10.0.0.101:9100')
            printer = GenericESCPOS(conn)
            printer.init()
            printer.text('Hello World!')
        
        File Print Example
        ----------------------
        
        This printer “prints” just into a file-handle. Especially on *nix-systems this comes very handy.
        
        This class is used for parallel port printer or other printers that are directly attached to the filesystem. Note that you should stay away from using USB-to-Parallel-Adapter since they are unreliable and produce arbitrary errors.
        
        .. sourcecode:: python
        
            from escpos.file import FileConnection
            from escpos.impl.elgin import ElginI9
        
            conn = FileConnection('/dev/usb/lp1')
            printer = ElginI9(conn)
            printer.init()
            printer.text('Hello World!')
            print printer.device.output
        
        
        Dummy Print Example
        ----------------------
        
        The Dummy-printer is mainly for testing- and debugging-purposes. It stores all of the “output” as raw ESC/POS in a string and returns that.
        
        .. sourcecode:: python
        
            from escpos.dummy import DummyConnection
            from escpos.impl.epson import GenericESCPOS
        
            conn = DummyConnection()
            printer = GenericESCPOS(conn)
            printer.init()
            printer.text('Hello World!')
        
            print printer.device.output
        
        
        
        Printing Barcodes
        -----------------
        
        There is a default set of parameters for printing barcodes. Each ESC/POS
        implementation will take care of the details and try their best to print your
        barcode as you asked.
        
        .. sourcecode:: python
        
            from escpos import barcode
            from escpos.serial import SerialConnection
            from escpos.impl.epson import GenericESCPOS
        
            conn = SerialConnection.create('COM1:9600,8,1,N')
            printer = GenericESCPOS(conn)
            printer.init()
            printer.code128('0123456789',
                    barcode_height=96, # ~12mm (~1/2")
                    barcode_width=barcode.BARCODE_DOUBLE_WIDTH,
                    barcode_hri=barcode.BARCODE_HRI_BOTTOM)
        
            printer.lf()
        
            printer.ean13('4007817525074',
                    barcode_height=120, # ~15mm (~9/16"),
                    barcode_width=barcode.BARCODE_NORMAL_WIDTH,
                    barcode_hri=barcode.BARCODE_HRI_TOP)
        
            printer.cut()
        
        
        The barcode data should be complete, that is, an EAN-13 barcode is formed from
        twelve digits plus check-digit. Most of the ESC/POS command implementations
        require only twelve digits and automaticaly calculate the check-digit.
        If you are dealing with, say, EAN-13 codes without the thirteenth-digit (the
        check-digit) just append zero (``0``) to the barcode class (or method) argument,
        so they can pass RE validation.
        
        .. sourcecode::
        
            printer.ean13('4007817525074')  # is OK
            printer.ean13('400781752507')   # raises ValueError
            printer.ean13('4007817525070')  # is OK and prints 4007817525074 as expected
