I installed brother_ql on Raspberry Pi 2 (Raspbian).
I test the main cmd:
$ brother_ql_create --model QL-500 ./720x300_monochrome.png > 720x300_monochrome.bin
and got this error:

Any response will be highly appreciated.
When installing the software, I have found that there is a problem right after installation: the brother_ql_* programs do not run from the command line. Is there something else I should be doing?
Hi Philipp,
Great work on this set of utilities, they work like a charm on my Brother QL-720NW.
I've created a tiny Bash function that combines your tools and Avahi into a single command to print a PNG (or similarly readable) image to a networked label printer. Feel free to include it or parts of it in your documentation.
The snippet:
https://gist.github.com/StefanHamminga/bb90fb318f87af5469a6e9ac46eab328
How likely is it that the QL-800 series works by just adding the relevant entries to devicedependent.py? It also has the ability to somehow print red on some labels - that probably needs extra work? I don't have the printer yet, but I need a printer for a project and I would get the 800 to test, if it is likely to work with brother_ql.
Hi,
Is there an argument to tell the script to print X number of labels of the same image?
Thanks!
I saw in the ReadMe that it's possible to have multiple pages in the bin file. Any chance you could point me in the right direction as to how that is done?
reader.py on line 10 is importing Numpy but it isn't needed/used in the module. Seems to be a leftover from old code that is causing errors since it's not installed.
System Mac OS X (10.11)
Printer QL-570

pip install pyusb

Is it possible to find an alternative not using pyusb in macos with this printer model?
Bug on pyUsb
I set up my env and in terminal I did:
(env) $ export BROTHER_QL_PRINTER=file:///dev/usb/lp0
(env) $ export BROTHER_QL_MODEL=QL-700
(env) $ brother_ql print -l 62 my_image.png
But every time I get NotImplementedError('Currently the printer can be specified either via an appropriate string or via an os.open() handle.')
I can verify that printing works because I tested it with the legacy CLI tools.
Hi,
Is there a solution using brother_ql to disable auto power off of the printer ?
I know it's possible using Windows or Mac utilities, but I'm working on a project which will use Brother printers at large scale and I would like to be able to disable it directly from linux, avoiding the need to pre-configure the printer.
Hey,
while creating the .bin-file I always get this message. It still work's but wanted to let you know that this occurs:

Hi,
Thanks for your awesome package, works like a charm!
There is however one thing, we've purchased a Brother QL-1060N, with address labels. The format looks like it's 102x152 mm, but it is 102x153 mm.
That means it flashes red when printing in the 102x152 format.
We've modified devicedependent.py ourselves, and added the extra label size, however if other people experience the same problem, permanent implementation in the repository would be great:
"102x153":{'tape_size': (102, 153), 'dots_total': (1200, 1804), 'dots_printable': (1164, 1660), 'right_margin_dots': 12, 'feed_margin': 0},
Keep up the good work!
Thanks for this cool library! It works almost perfect on my Raspberry Pi 3!
Anyway, I keep having this "AssesrtionError" prompting up after each successful printing. I wonder if it's my environment issue or the printer is not responding correctly?
/dev/usb)brother_ql_create -m QL-700 -s 62 /some/cat/image.png > test.binbrother_ql_print test.bin usb://0x04f9:0x2042After the print command, the image did printed on the label printer correctly, but in the console there is this assertion error:

Any idea?
The following code works perfectly (creates abc.bin file and prints from the printer) on command prompt:
brother_ql_create --model QL-800 --red abc.png --label-size 62> abc.bin
brother_ql_print abc.bin usb://0x04F9:0x209B
On python script:
from brother_ql import brother_ql_create
from brother_ql import brother_ql_print
from PIL.ImageTk import PhotoImage
brother_ql_create --model QL-800 --red abc.png --label-size 62> abc.bin_
Error: 'QL' is invalid syntax
Why is it not possible to call the following line on python script?
Is there any other method to create instruction file and print from script?
It would be great if you had a test script to create and print on your library.
Hi there!
I just found this awesome tool after losing my mind over brother drivers for a few hours and ran into some trouble with my QL-700 printer.
Printing a label fails somewhere halfway with hardware buttons becoming unresponsive until I restart the printer. The issue seems to be very similar to #11 from what I can tell.

Hello,
I'm trying to print to my QL-1050 on a 102x152 sticker.
When the job is sent, the printer LED turns blinking red.
Looking at the DEBUG Doc I was able to get the following information.
It looks like some response cannot be interpreted.
If you need further information, just tell me which command to run.
Thanks

Hi there, thank your for your awesome work! I am building stuff with a Raspberry Pi and a Brother QL-570 printer.
However, I have a problem when printing the generated bin. After printing, the printer won't cut the label off - and it also becomes unresponsive (not accepting any new print jobs) until I restart it with the power button. Seems like something isn't finished correctly.

After this, it takes a few seconds until the following shows up:

Any ideas on what might be causing this? Model number and label size is correct.
Thanks.
hi
how can i print if i have multiple devices with the same brand and product?
thank u
Hello there,
we have to create dynamic labels. Printing serial numbers onto devices. What would be a propper way to create and print them with brother_ql?
Thanks in advance
I think I didn't get the right resolution/size for the png file to convert.
Could you please provide a sample png file for a demo.
Need help please, dont know what am i doing wrong. The following line:
brother_ql_create --model QL-710W /home/administrador/etiquetas/etiqueta.png > /home/administrador/etiquetas/etiqueta_monochrome.bin
works when running the script from the command line, but outputs a file of length 0 when called by a cron script. Thank you.
Hi i run this command:
brother_ql print -l 62 tmp.png
And in terminal get:

But in printer error wrong roll type
Hello pklaus and thanks a lot for the awesome idea!
I am using QL-570 with Raspberry Pis as Invoice Printer, however, the cups drivers are less than usable and so I stumbled upon your tool - and really want to use it (as my input data is transfered as png files via python.. so.. could be good 👍)
However, the setup sadly does not work.
I am using an QL-570 with 54 / 590 / (54 mm endless) tape and the -to-be-wished- result would be an all page print out of the reciepe as seen in the added file. However, I only get an black square with the first file (cafe.png) and an black square with less "white space" / tape (cafe90.png). I included the bin files and png files as well.
And following errors:
root@demo:/home/pi/test# brother_ql_create --model QL-570 --label-size 54 ./cafe.png cafe.bin
root@demo:/home/pi/test# brother_ql_create --model QL-570 --label-size 54 ./cafe90.png cafe90.bin

You can download the file here https://jctixx.de/download/QL570Test.zip
If I can help you out with test prints or such, just let me know.
Also, I tried to play with the treshold setting - it did not make it less or more black :(
Hi,
is there a way to suppress following messages:

While trying to create 24mm diameter labels, an error about mismatching picture dimentions occurs.
Interesting is, when you add:
logger.warning(im.size[0]) logger.warning(im.size[1]) logger.warning(dots_printable[0]) logger.warning(dots_printable[1])
to "brother_ql_create.py", it will output 236 for each warning.
Anyhow, it will exit on:

I can call the command line from my python script just fine but I find that a little inelegant. I was hoping there might be some documentation of the functions and what to include that might save me having to trace through all the code and come up with such documentation myself.
I was using your package on an Aria G25 by Acme Systems (it's packed with a 400 MHz Atmel processor) to print to a QL-710W and it worked fine, the problem was speed: it took about 8 seconds to convert the png to raster and then print it.
I did some digging and found a pair of bottlenecks. The first one is the frame b/w invertion on the raster's add_raster_data function. That alone took around 5 seconds. The second one was the string concatenation of the raster data in the same function, which took around 2 seconds. So I made some workarounds and got the whole process to just over 1 second.
First, instead of doing your own inversion, you could lest Pillow invert the png just after resize:
im = PIL.ImageOps.invert(im)
Then, avoid string concatenation overhead using whatever better method you prefer. I did it by writing to a pseudo file and then setting the data to the file's value:
file_str = StringIO()
while start + row_len <= frame_len:
row = frame[start:start+row_len]
start += row_len
file_str.write(b'\x67\x00')
if self._compression:
row = packbits.encode(row)
file_str.write(bytes([len(row)]))
file_str.write(row)
self.data += file_str.getvalue()
There's one more optimization you may use in that loop if your device has more than once core (mine doesn't): you could parallelize the frame to data transfer. For example, if your device has 2 cores, just start 2 threads/processes and let each one deal with half the frame, then write to data in order. In my Aria of course that didn't help, but you should see an improvement in a Rasperry Pi, for example.
All this was tested with a CPython implementaion of Python 2.7. Anyway, just thought I should mention it if anyone is trying to use your package in a low-end device. If you like my proposals, I could clone your repo, make the changes and do a pull request, or you could just implement them yourself if you prefer. Let me know.
Cheers.
Hello,
first of all thanks for that great library.
But we have a problem by printing a round label (d24 -> 236x236).

Thank you for your help.
I'm getting the following error while printing a label on a QL-1060 on 4" endless tape:
usb.core.USBError: [Errno 60] Operation timed out
I think the issue is the 5 second timeout on line 70 in pyusb.py in backends is not high enough for slower print jobs. The job stops about 3/4s from finishing and the printer freezes up.

I'm able to print labels using the Brother P-Touch Editor via USB but I'm unable to do that via brother_ql. I've tried it on both Ubuntu and Windows 7 with both USB and the Linux Kernel.
Using the print or send command (eg. brother_ql -b pyusb -m QL-820NWB -p usb://0x04f9:0x209d print -l 62 test.png), I get usb.core.USBError: [Errno None] b'libusb0-dll:err [submit_async] submitting request failed, win error: The parameter is incorrect.\r\n'
It also happens when trying to send an instructions file. On Linux, I get a permissions denied error.
I was trying to print with my Brother QL810W in Ubuntu.

Am I doing anything wrong?
When I connect the Brother QL-800 to my Ubuntu 18.04 installation, the device appears as a mass storage device, rather than a printer. As a result, brother_ql does not list it as an available device. This occurs whether or not I have installed the Linux printer drivers. How can I tell Ubuntu to recognise the USB device as a printer rather than mass storage?

Right now I'm using the brother_ql_web with a Brother QL-1110NWB printer.
Unfortunately brother_ql doesn't recognize the QL-1110NWB model, but using the older QL-1050 works. I don't know if there need to be done any further modifications for this model to work properly. As far as I can tell the results seem to be good when using the QL-1050 config.
I get this error, I have installed brew install libusb and pip install pyusb
$ brother_ql_print --backend pyusb --list-printers
Traceback (most recent call last):

Using OSX and python 3.6
Installed the lastest dev version, noticed there is no way to get the current version installed of brother_ql
I wanted to confirm the functionality of the package with the QL-560.
Using to to automatically print labels for our PC inventory.
Thanks for the package!
When printing to my ql-1050 the program aborts after 2/3 of the image with:

Even with the above error it prints correctly.
I'm trying to print to a QL-500 printer attached to my router (which provides the print server) to a 62mm endless roll. When use netcat to send the printfile to the printer it works just fine. However when I use brother_ql_print only a the first line gets printed and then the printer needs to be resetted.
Debug output:
$ ./env/bin/brother_ql_print --debug --backend network test.bin tcp://192.168.1.1:9100
WARNING:brother_ql.brother_ql_print:The network backend doesn't supply any 'readback' functionality. No status reports will be received.
INFO:brother_ql.brother_ql_print:Sending instructions to the printer. Total: 290849 bytes.
DEBUG:brother_ql.backends.generic:Writing 290849 bytes.
The reported file size seems to be correct:
$ ls -l test.bin
-rw-r--r-- 1 andi users 290849 Oct 6 11:05 test.bin
I attached the print file and the original png here. test.zip
Is there anything I can to do help debugging this? From what I understand the network backend just opens a socket and then writes the whole content to it. Could it be that there is some buffering involved that needs to be flushed? (I'm not a python developer).
NOTE: Do not merge without a 3.0 fix (it's a 2.7 only fix)
https://github.com/spidfire/brother_ql/blob/master/brother_ql/reader.py
during the use of brother_ql_print it got an error of unable to convert str to int
I've created a python 2.7 fix (it doesn't work with py3+)
it fixes the problem of that a bytearray element like data[1] returns a string in 2.7 and a int in 3+
