Can I control my Canon printer over Wi-Fi from my phone?

It's not quite as straightforward as you might think - it really depends on your printer model.

With most newer Canon printers that have Wi-Fi, you can print from your phone using the Canon PRINT app, but you'll need to connect the printer to the same network first and install the app.

Some older models don't support this at all or only very limited functionality, so it's best to check the user manual to see if your printer is compatible.
