Has anyone Printed a Panorama\Banner using a Canon ix6820 printer?

I have a canon ix6820 printer that I use to make prints of my artwork and I recently did a canvas piece that was longer but was not possible to make prints since the largest size option on the printer is 13x19. So I was wondering if there was a program i could use to print through that would allow printing on a longer scale say like 12x30 or if it is simply not possible with my current printer
