Overview

Cat printer is a portable thermal printer sold on AliExpress for around $20.

This repository contains Python code for talking to the cat printer over Bluetooth Low Energy (BLE). The code has been reverse engineered from the official Android app.

Installation

# Clone the repository.
$ git clone [email protected]:rbaron/catprinter.git
$ cd catprinter
# Create a virtualenv on venv/ and activate it.
$ virtualenv --python=python3 venv
$ source venv/bin/activate
# Install requirements from requirements.txt.
$ pip install -r requirements.txt

Usage

$ python print.py --help
usage: print.py [-h] [--devicename] [--log-level {debug,info,warn,error}] [--img-binarization-algo {mean-threshold,floyd-steinberg}] [--show-preview] filename

prints an image on your cat thermal printer

positional arguments:
  filename

optional arguments:
  -h, --help            show this help message and exit
  --devicename          Specify the Bluetooth device name to search for. Default value is GT01.
  --log-level {debug,info,warn,error}
  --img-binarization-algo {mean-threshold,floyd-steinberg}
                        Which image binarization algorithm to use.
  --show-preview        If set, displays the final image and asks the user for confirmation before printing.

Example

% python print.py --show-preview test.png
⏳ Applying Floyd-Steinberg dithering to image...
✅ Done.
ℹ️ Displaying preview.
🤔 Go ahead with print? [Y/n]?
✅ Read image: (42, 384) (h, w) pixels

Support Printing Text
Hey, thank you for putting all this together, what a great idea.

There is #42 which talked about the idea of printing text, but nothing was implemented and the linked PR isn't the solve.

What I would like is I could issue a command like

python print.py --message "Its Hack 'o Clock"

And it would print something very close to the image in the repo.

With this, my hope is to create a silly shopping list creator. Glue a magnet to the back of this badboy, pop it on the fridge, then send a text/email/tweet, "Buy more peanut butter". Tear it off on your way to the store. Voila, shopping list creator.

add short options, allow abbreviating binarization_algo

I hate typing, and ./print.py -b h -s cat.jpg feels soo much better than the long version.

This assumes that binarization algos will always starting with a unique letter.

Finding the BLE device name

This might be a silly question, but I'm not able to find the printer (Using MacOS). Is there any particular way to know what the name of the BLE device is?

Other device names than GT01 are possible
I see you've hard-coded the device search to GT01, with my cat printer the device name is GB02.

I bought my cat printer from Wish.com, it's a "Wirelessly BT 203dpi Mini Thermal Printer Photo Label Memo Wrong Question Printing with USB Cable imprimante portable".

After some searching around and looking at other cat printer_-related_ projects, there are a few variations: GB01, GB02, GT01

Visually the device looks identical to yours. It uses the same iPrint software from the Google Play Store.

Changing the hard-coded GT01 to GB02 in ble.py seems to make the script work with my cat printer.

iTerm2 crash when trying to access Bluetooth

edit: not catprinter's fault, see followup comment

(macOS 12.3 on M1 Pro, Python 3.10.2, zsh 5.8, iTerm2 3.5.0beta2)

The installation instructions worked great, but the script is crashing when trying to actually connect to bluetooth devices:

$ python3 print.py --show-preview test.jpg
⏳ Applying Floyd-Steinberg dithering to image...
✅ Done.
ℹ️  Displaying preview.
🤔 Go ahead with print? [Y/n]?
✅ Read image: (386, 384) (h, w) pixels
✅ Generated BLE commands: 14851 bytes
⏳ Trying to auto-discover a printer...
zsh: abort      python3 print.py --show-preview test.jpg

(screenshot)

The crash log includes the following:

Termination Reason:    Namespace TCC, Code 0 
This app has crashed because it attempted to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSBluetoothAlwaysUsageDescription key with a string value explaining to the user how the app uses this data.

— it seems like this should be an easy fix, or maybe even a permission I can override myself at runtime, but I'm not familiar enough with macos dev to know how, and having trouble googling for the right answer here. I'd find it super valuable to include the needed file(s) or just some readme instructions in this repo.

Feature none binarization

Hello, I propose to add an option to disable the binarization which could be helpful in some cases.

The added code assumes that the image uses a correct width of PRINT_WIDTH = 384.

If you have any remarks on this pull request I am happy to incorporate them.

Added dark mode for advanced print quality

the printer can now print in 'text mode' if the --darker flag is set. This makes the print a bit slower, but the contrasts are much higher. Here is an example:

Added halftone dithering algorithm

Hi! Thanks for your cool project. I really liked playing around with this cool printer. One addition: I've added another binarization method - it's not as advanced as floyd-steinberg, but I liked it's artistic look.

Thanks to @GravO8 - I've borrowed your algorithm 👍

Security Fixes

Pinned Dependencies

A pinned dependency is a dependency that is explicitly set to a specific hashed version instead of a mutable version. Pinned dependencis ensure that development and deployment are done with the same software versions which reduces deployment risks, and enables reproducibility. It can help mitigate compromised dependencies from undermining the security of the project in certain scenarios. The dependencies were pinned using Secure WorkFlows

cmd_feed_paper, cmd_set_energy, dark_mode seem to have no effect

When trying to implement cmd_set_energy and cmd_feed_paper in my own application, changing the values used in cmds_print_img function appears to have no effect. The paper doesn't feed any further, and/or the text is not any darker if I increase the values in these fields.

Printing a demo page from the iOS App (or the built-in debug QR code print mechanism) provides much darker prints than printing a black text on white BG PNG from catprinter. I suspect that these values are not being properly set when I print from the function vs. the App.

Printer model: GB02

CUPS support

Hi, one thing could make this printer even more awesome: network printing!

What is the difficulty of creating a CUPS filter able to print through this cat thingy?

Can't print on uncommon printer model

According to the QR code information page that prints out, my device's name is YHK-9B51 (instead of the more common GB01, GB02, etc). It seems the last four digits of the device name come from the mac address which ends in :9B:51. However, when I use bleak to scan devices, what shows up under the name "YHK-9B51" has a completely different MAC address ending in :C4:AD. (Specifically, when I try to pair the printer in Windows, two copies of "YHK-9B51" show up. One pairs but doesn't connect, and the other always rejects a connection. I'm not sure if any of that info is helpful, it is just things I've found while troubleshooting.

Anyways, when I run the print script with devicename set to YHK-9B51, sometimes it exits with exception asyncio.exceptions.TimeoutError and other times it first says Connected: True; MTU: 508 and then exits with exception bleak.exc.BleakError: Characteristic 0000ae01-0000-1000-8000-00805f9b34fb was not found! Could this be a newer hardware revision that's not compatible with the program, and if so, is there any data I could provide to help support it? (Also, I also tried this on macOS 12 Monterey, but bleak does not show any devices whatsoever because bleak currently doesn't support Monterey: https://github.com/hbldh/bleak/issues/635)
