Unable run due to error "AttributeError: module 'socket' has no attribute 'AF_BLUETOOTH'"

Any ideas how to fix ? Installed "original" from python.org - had to downgrade from 3.12 to 3.11 (?!) as well as brew version and both give the same error... help please

[TheZoc]

AF_BLUETOOTH isn't available on macOS (as far as I could find out on Google) - Bluetooth support would added using CoreBluetooth API.

In the short term, you can try using the serial connection through a USB connection. You'd need to find your serial port - in the format described in README.md - and add it to the command line.
Optionally, you can try this experimental fork with auto detection on serial port, but keep in mind it wasn't tested in macOS yet: https://github.com/TheZoc/niimprint

Oh... I didn't even bother reading the USB part as B1 has no USB connection...Silly of me.

So choosing usb and providing the /dev/tty.B1-.... address does connect to the printer (it beeps and LED changes color!), but there

in set_label_density
   return bool(packet.data[0])

(printer.py", line 253,) error...

It sure is a step forward. A big one.

[TheZoc]

I also have a B1 :)
Could you paste the entire error message for me, please?

This is an interesting one.
I got my old MacBookPro (late 2013) and tried with Python 3.12. I currently have Big Sur installed.

I wrote a simple script to list the serial ports on my mbp and it would randomly fail to list my B1 printer in there. I couldn't find a pattern to why.
Strangely enough, when I put that detection in a loop, it didn't fail once. Even played with random sleep() times to see if I could make it fail consistently - but it didn't. Removing the loop and calling the program through the command line would cause it to randomly fail again.

I even managed to see it was missing once with ls -la /etc/tty*

Upon trying multiple times, when I connect to it, I usually get "OSError: [Errno 6] Device not configured". I did try using my fork as well, as it has more checks, but no success. By spamming the command I couldn't print the sticker once :/

Hopefully someone more experienced with RS232 and macOS can contribute here

[MoonshineSG]

i think this is kinda obvious, but i’ll still say it… i had the mac connected to the b1 via bluetooth first.. then ran the cook and line to print…

[MoonshineSG]

I gave up running it over a Mac, and setup an old RPi... Connection over Bluetooth works fine, but it just prints a blank label ... So close... 😂😂

tried different "D" params, all with the same result

[TheZoc]

Looks like a duplicate of #17
Try printing with a serial cable if you can, it will probably work :)

[MoonshineSG]

cable? b1 supports USB printing? 🤔

[TheZoc]

It does - and I thought you attempted to do that when you used the parameter -c usb 😅

A somewhat shameless plug, I'm currently maintaining a fork that has more cable/serial/usb capabilities such as auto-detection. Works great on windows, but seems to have the same issues on macOS. Hopefully it will work nicely in Linux as well: https://github.com/TheZoc/niimprint

[AndBondStyle]

@TheZoc I'm experiencing a severe lack of time recently, but it would be nice if we can merge at some point :)

[MoonshineSG]

the usb address /dev/tty.B1… was created by the bluetooth connection … I will try again… and will try the fork as well

[TheZoc]

@AndBondStyle Happy to have it merged if you like the changes and code style :)
I'm trying to use ruff to format it and keep it to a standard, but some of the formulas being broken in multiple lines are annoying me right now :(

[TheZoc]

@MoonshineSG I wasn't aware macOS would convert a bluetooth device to a USB-like port, interesting.
Hoepfully the fork and the cable solution solves the issue :)

[MoonshineSG]

@TheZoc so found couple of errors in your fork, but all in the '_detect_port_and_model' which I don't need, so I just removed that whole function. And it work! It printed nicely but only via USB. I would prefer BT, but I can live with the USB as well. Thanks for the help.

[TheZoc]

Oh thanks for the report. It seems I did use double quotes inside double quotes and that's apparently only supported in python 3.12

Not sure why I missed that port not being self._port as well, and why it's working locally o.O

I'll add a fix for both of those tomorrow :)

@MoonshineSG
Please let me clarify since the issue has been closed.
Have you successfully printed from macOS via USB-C?
According to the logs, it seems like you are using a Raspberry Pi after all.

No, I gave up on trying on MacOS...
