The Canon SELPHY CP740 is a compact photo printer that uses dye-sublimation technology to produce prints from digital images. Its driver lets Windows communicate with the printer and provides access to settings such as paper size, orientation, and print layout when printing from a computer.

Key Features

• Computer-to-printer communication: Enables compatible Windows software to send photo print jobs to the Canon SELPHY CP740 over USB.
• Photo print settings: Provides controls for supported paper formats and layouts, helping you match the print job to the loaded paper and ink cassette.
• Application integration: Makes the printer available through the print menus of compatible photo viewers, image editors, and other Windows programs.
• Print queue support: Works with Windows printing controls so you can monitor pending jobs and cancel unwanted prints.

How to Install

1. Check compatibility before downloading. Confirm your Windows version and whether your system is 32-bit or 64-bit. If you use Windows 11, 10, 8, or 7, verify that the specific driver package explicitly supports your setup. This is an older printer, so a legacy driver should not be assumed to work on every newer Windows version.

1. Prepare the printer. Load the correct paper and matching ink cassette, connect the power adapter, and turn on the SELPHY CP740. Leave the USB cable disconnected from the computer until the installer requests it, unless the package instructions say otherwise.

1. Run the driver installer. Extract the downloaded package if necessary, open its setup program, and approve the Windows permission prompt. Follow the on-screen instructions and select the appropriate connection option if prompted.

1. Connect the USB cable. Attach the printer directly to an available USB port when instructed. Allow installation to finish before opening a photo application or starting a print job.

1. Check settings and test a photo. Open Windows printer settings and confirm that the Canon SELPHY CP740 appears. Select it in your application, choose the paper size that matches the loaded media, and print a test image.

If installation fails or the printer is not detected, check the USB connection and the package’s compatibility notes. Windows compatibility mode is not a guarantee that an unsupported printer driver will function correctly.

Common Issues and Fixes

• Install fails or stalls: Disconnect the CP740 before running the installer, then run it as administrator. Temporarily pause antivirus and use the Canon SELPHY CP740 package—not a generic SELPHY or Windows photo-printer driver.
• Device not detected: Power on the CP740 and connect it directly to a rear USB port, not a hub. Try another USB cable, check Device Manager for an unknown device, then reinstall the driver.
• Version conflicts: Remove older Canon SELPHY drivers and any stale CP740 printer entries in Devices and Printers. Reboot, then install the latest CP740 driver so Windows doesn’t fall back to a generic driver and affect print quality.
