Cant open main.py and (or just) server.py

[Eduardfabian21]

When ever i try to open it says this Im using: Windows 10 Home version 22H2 Latest version of Python Latest version of Cat Printer

[Eduardfabian21]

• i forgot to say that i also tryed bare one

[AndCouvel]

same here

[NaitLee]

Are you sure it’s the latest version of Python? Try python3 --version to see the interpreter version.

By the way, try if this snippet will work:

a = 10
while a := a - 1:
    print(a)

The := operator is added in Python 3.8, it should be earlier versions showing a Syntax Error.

[Eduardfabian21]

To my surprize, it outputed: Python 3.7.9

[NaitLee]

As far as I can remember, on Windows, typical command to invoke Python is py.

I don’t know about old versions, probably an old version was kept for python3 in your case (and probably by something else.)

I tryed with 3.10.10 and it says: Traceback (most recent call last): File "C:\Users\Edi\Downloads\cat-printer-pure-0.6.2.0\cat-printer\main.py", line 3, in <module> from server import serve File "C:\Users\Edi\Downloads\cat-printer-pure-0.6.2.0\cat-printer\server.py", line 22, in <module> from printer import PrinterDriver, PrinterError, i18n, info File "C:\Users\Edi\Downloads\cat-printer-pure-0.6.2.0\cat-printer\printer.py", line 78, in <module> raise error File "C:\Users\Edi\Downloads\cat-printer-pure-0.6.2.0\cat-printer\printer.py", line 74, in <module> from bleak import BleakClient, BleakScanner File "C:\Users\Edi\Downloads\cat-printer-pure-0.6.2.0\cat-printer\bleak\__init__.py", line 73, in <module> from bleak.backends.winrt.scanner import ( File "C:\Users\Edi\Downloads\cat-printer-pure-0.6.2.0\cat-printer\bleak\backends\winrt\scanner.py", line 6, in <module> from bleak_winrt.windows.devices.bluetooth.advertisement import ( ModuleNotFoundError: No module named 'bleak_winrt'

And on windows you can still use python3 cmd EVEN if its a newer version

[Eduardfabian21]

If i use py main.py, it opens a new windows

[Eduardfabian21]

and i forgot to say that, windows forces me to download it from the windows store

[NaitLee]

You may install Python dependencies with pip. Cat-Printer is using bleak (along with bleak_winrt, on Windows.)

pip install bleak

It’s a pity that I’m unable to setup a good Windows bundle in a long time.

[NaitLee]

btw main.py is unimportant, it’s just a helper script for Android and does nothing special other than “executing” server.py by importing.

It outputed:

I also saw that you still need python for the older ver of cat-printer

[NaitLee]

Seems the pure bundle have outdated dependency.

You may want the bare bundle, or simply clone the repository.

That batch script is intended for a complete Windows bundle (available for some earlier versions), where an embeddable Python 3 is included (and that’s named python.exe, hence python)

Hi @AndCouvel, I didn’t see Python 3.11.2 problems here. You may send some snapshots to show what’s exactly going on your side :)

In case technology is a problem, just use this new Web app: https://print.unseen-site.fun/

Be sure to use a Chromium-based browser for it. Safari is probably ok too.
