PIXMA PRO-200 Borderless Printing for Square Greeting Cards

[AlaskanAccents]

I need to print 5.25" x 5.25" square greeting cards, but it's looking like borderless is not an option?

Borderless printing is only available for standard paper size for the printer. 
Borderless printing oversprays the paper to ensure that the entire page is covered. There are sponges in the printer to absorb the overspray. They are located for standard paper sizes listed in the printer specs.
