Does the type of paper I use really make a difference?

• The CX6600 will work with a variety of papers and media. However, we recommend using Epson media for the best results.
  
  Epson Matte Paper Heavyweight and Epson DuraBrite Ink Glossy Photo Paper have been developed to produce the highest-quality output with DuraBrite inks. For optimum image quality and longest print life (up to 70 years), print your photos with Epson Matte Paper Heavyweight.
  
  Other brands of paper may not work as well with DuraBrite inks. They will not have the longevity of Epson's long-lasting media and may produce lower-quality images. The ink also may not dry properly.
