Hello.
The WPS button is not on the printer. This button would be located on your router itself.
If your router does not have a clearly marked 'WPS' button, please reply with the printer model you have, and the version of Windows or Mac in use, so our community can further assist!
If this is a time-sensitive matter, please contact us at 1-800-OK-CANON, weekdays between 10 AM and 10 PM ET (7 AM to 7 PM PT).
Thanks and have a great day!
