Cat-Printer

A friendly cat (kitty) printer App/driver for everyone (GB01,GB02,GT01)

(According to official website, maybe there are also normal-, piggy- and frog-shaped printers with these models)

Features

• Print jpg/png images directly to cat printer from a web interface
• Print a document (.doc, .docx, .odt etc) by copy-paste
• Custom print content, put text, image, QRcode on a canvas
• (more will be here...)

How to use

On Windows 10:

• Get a release, extract, open start.bat.
• Make sure bluetooth of your computer is opened and cat printer is launched.

On GNU/Linux:

• You can also use a Windows release, or prepare dependencies according to developer note.
• Open server.py in printer folder with python3.

Notes:

• Newest Firefox users need to manually allow the permission of extracting canvas data, at left side of address bar after clicking preview button
• Windows version needs to be at least 10 (10.0.16299)
• GNU/Linux needs BlueZ (bluetoothctl)
• Maybe also compatible to Mac (Darwin) with CoreBluetooth Framework

Why?

These bluetooth cat printers, with model name GB01, GB02 and GT01, have poor support at applications.

Official apps are, proprietary, also have only mobile version.

I hate both proprietary and platform-binding things. So I decided to make this.

Thankfully, people here are really warm-hearted, logged their experiences online in a central repo, and I am able to walk further 😃

Trivial

• Many one choose these cat thermal printers because they are cute... or, just cheap 🙃

• Here we tell "Cat Printer" because other developers also call the printer as this, but what oversea shops call is "Kitty Printer". Search engines, please optimize it 😝

• The official app is protected by law & copyright. I don't know if my work is not good...

Developer Note

This application uses server/client model, and have fewest possible dependencies on server side.

Prepare

• Python3 & Browser
• fabric.min.js
• html2canvas.min.js
• qrcode.min.js
• (Optional) Any css for plain webpage, e.g. minicss, rename to skin.css

Put any web-related files to folder www.

Supported Platforms

Support for both Windows and GNU/Linux are included. And Windows release package will contain all needed things for a normal user to play with.

Plans

• Smoother mono-color converting
• Make remote-print by web interface more standard/compatible/secure

Possible features:

• Remote print with printer protocols

Files

• server.py: Contains a BaseHTTP server that hooks user actions and printer driver
• printer.py: Contains the driver of bluetooth cat printer, which depends on bleak. You can also run this file in commandline.
