Description: brother\_ql
        -----------
        
        A Python package to control Brother QL label printers. It implements the
        raster language of those printers and allows you to send instruction
        files to your printer. In more details, the following is possible with
        this package:
        
        -  Create raster language files for the Brother label printers. They can
           be created from image files or programmatically in your own Python
           script.
        -  Print raster instruction files with your Brother label printer via
           different backends:
        
           -  pyusb (works cross-platform)
           -  network (works cross-platform for WiFi/Ethernet-enabled printers)
           -  linux\_kernel (works on Linux only; uses the /dev/usb/lp0 device
              handles)
        
        The following printers are claimed to be supported (✓ means verified by
        the author or by contributors):
        
        -  QL-500 (✓), QL-550 (✓), QL-560, QL-570 (✓), QL-580N, QL-650TD, QL-700
           (✓), QL-710W (✓), QL-720NW (✓), QL-800 (✓), QL-810W, QL-820NWB (✓),
           QL-1050 (✓), and QL-1060N.
        
        The new QL-800 series can print labels with two colors (black and red)
        on DK-22251 labels.
        
        Note: If your printer has an 'Editor Lite' mode, you need to disable it
        if you want to print via USB. Make sure that the corresponding LED is
        not lit by holding the button down until it turns off.
        
        If you're interested in printing labels using a web interface, have a
        look at my project
        `brother\_ql\_web <https://github.com/pklaus/brother_ql_web>`__. It
        makes use of the brother\_ql package and is also written in Python.
        
        Why
        ---
        
        The special feature of this package is that no printer driver is
        required for it to work. This software bypasses the whole printing
        system including printer drivers and directly talks to your label
        printer instead. This means that even though Brother doesn't offer a
        driver for the Raspberry Pi (running Linux on ARM) you can print nicely
        using this software. And even if there are drivers for your operating
        system, many programs have difficulties to set the page sizes and
        margins for the labels correctly. If you want to print with high
        precision (which is important for barcodes for example), you rather want
        to have control about every single pixel to be printed. This is where
        brother\_ql comes into the game.
        
        Installation
        ------------
        
        brother\_ql is available from PyPI with pip:
        
        ::
        
            pip install brother_ql
            # or to upgrade to a newer release:
            pip install --upgrade brother_ql
        
        Alternatively, you can install the latest development version from
        Github using:
        
        ::
        
            pip install --upgrade https://github.com/pklaus/brother_ql/archive/master.zip
        
        This package was mainly created for use with Python 3. The essential
        functionality, however, will also work with Python 2: the creation of
        label files.
        
        Usage
        -----
        
        The main user interface of this package is the command line tool
        ``brother_ql``.
        
        ::
        
            Usage: brother_ql [OPTIONS] COMMAND [ARGS]...
        
              Command line interface for the brother_ql Python package.
        
            Options:
              -b, --backend [pyusb|network|linux_kernel]
              -m, --model [QL-500|QL-550|QL-560|QL-570|QL-580N|QL-650TD|QL-700|QL-710W|QL-720NW|QL-800|QL-810W|QL-820NWB|QL-1050|QL-1060N]
              -p, --printer PRINTER_IDENTIFIER
                                              The identifier for the printer. This could
                                              be a string like tcp://192.168.1.21:9100 for
                                              a networked printer or
                                              usb://0x04f9:0x2015/000M6Z401370 for a
                                              printer connected via USB.
              --debug
              --help                          Show this message and exit.
        
            Commands:
              analyze   interpret a binary file containing raster...
              discover  find connected label printers
              info      list available choices (for labels or models)
              print     Print a label
              send      send an instruction file to the printer
        
        There are some global options available such as --model and --printer.
        They can also be provided by environment variables (``BROTHER_QL_MODEL``
        and ``BROTHER_QL_PRINTER``).
        
        The global options are followed by a command such as ``info`` or
        ``print``. The most important command is the ``print`` command and here
        is its CLI signature:
        
        ::
        
            Usage: brother_ql print [OPTIONS] IMAGE [IMAGE] ...
        
              Print a label of the provided IMAGE.
        
            Options:
              -l, --label [12|29|38|50|54|62|102|17x54|17x87|23x23|29x42|29x90|39x90|39x48|52x29|62x29|62x100|102x51|102x152|d12|d24|d58]
                                              The label (size, type - die-cut or endless).
                                              Run `brother_ql info labels` for a full
                                              list including ideal pixel dimensions.
              -r, --rotate [auto|0|90|180|270]
                                              Rotate the image (counterclock-wise) by this
                                              amount of degrees.
              -t, --threshold FLOAT           The threshold value (in percent) to
                                              discriminate between black and white pixels.
              -d, --dither                    Enable dithering when converting the image
                                              to b/w. If set, --threshold is meaningless.
              -c, --compress                  Enable compression (if available with the
                                              model). Label creation can take slightly
                                              longer but the resulting instruction size is
                                              normally considerably smaller.
              --red                           Create a label to be printed on
                                              black/red/white tape (only with QL-8xx
                                              series on DK-22251 labels). You must use
                                              this option when printing on black/red tape,
                                              even when not printing red.
              --600dpi                        Print with 600x300 dpi available on some
                                              models. Provide your image as 600x600 dpi;
                                              perpendicular to the feeding the image will
                                              be resized to 300dpi.
              --lq                            Print with low quality (faster). Default is
                                              high quality.
              --no-cut / --cut                Don't cut the tape after printing the label.
              --help                          Show this message and exit.
        
        So, printing an image file onto 62mm endless tape on a QL-710W label
        printer can be as easy as:
        
        ::
        
            export BROTHER_QL_PRINTER=tcp://192.168.1.21
            export BROTHER_QL_MODEL=QL-710W
            brother_ql print -l 62 my_image.png
        
        The available label names can be listed with ``brother_ql info labels``:

             d58        618 x  618    58mm round die-cut
        
        **Pro Tip™**: For the best results, use image files with the matching
        pixel dimensions. Die-cut labels have to be in the exact pixel
        dimensions stated above. For endless label rolls, you can provide image
        files with a pixel width as stated above. If you provide a file with
        different dimensions when creating an endless label file, it will be
        scaled to fit the width.
        
        Legacy command line tools
        ~~~~~~~~~~~~~~~~~~~~~~~~~
        
        For a long time, this project provided multiple command line tools, such
        as ``brother_ql_create``, ``brother_ql_print``, ``brother_ql_analyze``,
        and more. A documentation of their usage can be found in the
        `LEGACY <https://github.com/pklaus/brother_ql/blob/master/LEGACY.md>`__.
