To set up and connect your Canon TS3720 printer, you can use the official Canon support website at ij.start.canon/connect, which offers detailed instructions and software downloads for Windows, Mac, Android, and iOS devices[1]. For example, if you are connecting on Windows 10 or later, you can access the Microsoft Store to download the required app, or on other OS, use the web instructions provided at that URL[1].

Additionally, Canon USA provides step-by-step video guides for wireless setup on different platforms:
– For iOS devices, install the Canon Print app from the App Store, then use it to connect the printer to your wireless router[2].
– For Mac, launch the setup software, agree to the license, select Wi-Fi connection, press and hold the wireless connect button on the printer for 3 seconds, confirm your Wi-Fi network, and complete the installation[3].
– For Windows, run the setup software, select Wi-Fi connection, press the wireless button on the printer for 3 seconds to detect it, confirm the Wi-Fi network, and proceed with installation, including optional test printing[4].

If you use Chrome OS, Canon provides connection instructions specifically for that platform on their manual page[5].

In summary, start by visiting https://ij.start.canon/connect from the device you want to print from, then follow the tailored instructions or use the Canon Print app for mobile devices. The wireless connect button on the printer is pressed for 3 seconds during setup to enable the network connection mode[1][2][3][4].
