Troubleshooting Wireless IAP Driver Issues with Canon Selphy CP900

--------------------------------------------------------

If you're experiencing problems printing or displaying images from your Canon Selphy CP900 using a computer's Wi-Fi connection after editing them in Adobe Photoshop, it may be related to an issue with the wireless iap driver.

Symptoms of this problem include:

- A question mark instead of image preview on the printer's screen

- Failure to print edited photos

To troubleshoot and potentially resolve these issues, follow these steps:

1. Check Wi-Fi Connection: Ensure your Canon Selphy CP900 is properly connected via a stable wireless network.

2. Update Wireless iap Driver:

- Open Device Manager or Control Panel > Hardware & Sound (depending on Windows version).

- Under 'Ports' section, look for the device listed as 'Canon SelPHY USB Printer'.

- Right-click and select 'Update driver'.

3. Clear Print Queue:

- Press 'Print' button twice to open Print Properties.

- Click 'Cancel' if a printer is selected.

4. Restart Canon Selphy CP900 & Computer:

- Turn off the printer, wait for 30 seconds.

- Reboot your computer.

If none of these steps resolve the issue or you continue experiencing problems printing edited images from Photoshop using Wi-Fi with your Canon Selphy CP900, it may be worth contacting either Canon's customer support team or a professional repair service to rule out any hardware defects within the printer itself.
