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, check out `brother_ql_web <https://github.com/pklaus/brother_ql_web>`__, which builds upon this package. 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 on the Python Package Index <https://pypi.python.org/pypi/brother_ql>`__ to be installed with pip: :: pip install --upgrade brother_ql The upgrade flag makes sure, you get the latest version of brother_ql but also of its dependencies. Alternatively, you can install the latest 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. In order to run the ``brother_ql`` command line utility, the directory it resides in needs to be in the PATH envirnoment variable. On some systems, the ``pip install`` command defaults to the ``--user`` flag resulting in the utility being put in the ``~/.local/bin`` directory. On those systems, extending the path variable via ``export PATH="${PATH}:~/.local/bin"`` is needed. 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 --version Show the version and exit. --help Show this message and exit. Commands: analyze interpret a binary file containing raster... discover find connected label printers info list available labels, models etc. 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 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``: :: Name Printable px Description 12 106 12mm endless 29 306 29mm endless 38 413 38mm endless 50 554 50mm endless 54 590 54mm endless 62 696 62mm endless 102 1164 102mm endless 17x54 165 x 566 17mm x 54mm die-cut 17x87 165 x 956 17mm x 87mm die-cut 23x23 202 x 202 23mm x 23mm die-cut 29x42 306 x 425 29mm x 42mm die-cut 29x90 306 x 991 29mm x 90mm die-cut 39x90 413 x 991 38mm x 90mm die-cut 39x48 425 x 495 39mm x 48mm die-cut 52x29 578 x 271 52mm x 29mm die-cut 62x29 696 x 271 62mm x 29mm die-cut 62x100 696 x 1109 62mm x 100mm die-cut 102x51 1164 x 526 102mm x 51mm die-cut 102x152 1164 x 1660 102mm x 153mm die-cut d12 94 x 94 12mm round die-cut d24 236 x 236 24mm round die-cut 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. Backends ~~~~~~~~ There are multiple backends for connecting to the printer available (✔: supported, ✘: not supported): ============ ==== ======= ======= ======= Backend Kind Linux Mac OS Windows ============ ==== ======= ======= ======= network (1) TCP ✔ ✔ ✔ linux_kernel USB ✔ (2) ✘ ✘ pyusb (3) USB ✔ (3.1) ✔ (3.2) ✔ (3.3) ============ ==== ======= ======= ======= Notes: 1. The network backend doesn’t support reading back the printer state, currently. Failure such as *wrong label type* or *end of label roll reached* won’t be detected by this software. 2. The label printer should show up automatically as ``/dev/usb/lp0`` when connected. Please check the ownership (user, group) of this file to be able to print as a regular user. Consider setting up a udev .rules file. 3. PyUSB is a Python wrapper allowing to implement USB communication in userspace. 1. On Linux: install libusb1 as offered by your distribution: ``sudo apt-get install libusb-1.0-0`` (Ubuntu, Debian), ``sudo zyppe in libusb-1_0-0`` (OpenSUSE), ``sudo pacman -S libusb`` (Arch). 2. On Mac OS: Install `Homebrew <https://brew.sh/>`__ and then install libusb1 using: ``brew install libusb``. 3. On Windows: download `libusb-win32-devel-filter-1.2.6.0.exe <https://sourceforge.net/projects/libusb-win32/files/libusb-win32-releases/1.2.6.0/>`__ from sourceforge and install it. After installing, you have to use the “Filter Wizard” to setup a “device filter” for the label printer. 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. The overview of those tools can still be found in the `LEGACY <https://github.com/pklaus/brother_ql/blob/master/LEGACY.md>`__ documentation. The use of these tools is now considered deprecated and they will be removed in a future release.
