Depending on your disc label manufacturer, you may need to use a set of specific settings, a template or a special application to print your label. Since you are basically printing on a formatted piece of 8 1/2 x 11, the printer will be handling the labels like a normal sheet of paper. For this type of print job, My Image Garden is not ideal.
A great feature of the PIXMA Pro-100 is the ability to print directly onto specially coated CD/DVD/BD discs. With My Image Garden, you can format and design your label and have the final design applied directly to the disc. More information can be found in the manual for My Image Garden.
