A lot of people are confused by the Print and Cut feature. The Silhouette cannot print. How the print and cut feature works is through the printer you have connected to your computer. Mine is a regular inkjet HP printer. When you are in the Silhouette Studio software, there is a button called "send to printer". This will send the image on your mat to the printer connected to your computer. You will use that printed image, place it on your mat and insert it into the Silhouette for cutting.
Hope this helps a few of the questions that have been rolling in.
