Ivy 2

20230516_133925

A Python API to control the Canon Ivy 2 mini photo printer.

Note: So far, this has only been tested on a Raspberry PI 3b+. The underlying PyBluez library should be cross-compatible but the pairing process will likely vary from platform to platform.

Installation steps (Raspberry PI)

  1. Install deb packages
sudo apt install bluetooth bluez libbluetooth-dev
  1. Install pip packages
pip install -r requirements.txt
  1. Disable legacy pairing

This will need to be done each time the computer reboots. Otherwise you may get an "Invalid exchange" error when trying to connect with the printer.

sudo hciconfig 0 sspmode 0
  1. Pair with the printer

This only needs to be done the first time.

Start the BlueZ CLI

bluetoothctl

If this is your first time messing with Bluetooth on the PI, first register an agent:

  • agent on
  • default-agent

Turn on the printer and wait about 30 seconds. Then enable scanning:

  • scan on

You should start to see local Bluetooth devices popping up. Most of the devices will just show a mac address but the printer should have the name listed as well making it easy to spot. You should see something like this:

[NEW] Device 04:7F:0E:B7:46:0B Canon (46:0B) Mini Printer
             ^ mac address

Once you've located the printer, take note of the mac address and attempt to pair:

  • pair <mac-addr>
  • trust <mac-addr>

You can now disable scanning and exit the BlueZ CLI:

  • scan off
  • exit

Usage

See example.py for basic usage.
