This is the only program on my computer from which I cannot print. I am using a Canon Pixma MG 3150 which is connected through a WiFi network. How can I solve this?
It's possible that you can't print using the Serif product because some options will not permit this. Before you do anything else, check the following guide regarding printing and try again. If this didn't solve your problem, check the official support page or contact the developer for further support.
