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

• The ink in this printer works great on inexpensive uncoated paper for your everyday printing needs.
  
  For high quality printouts and for long lasting images such as photos, it is important to use genuine EPSON brand paper.
  EPSON brand paper has been specifically developed to be compatible with the ink formula used in EPSON printers.
  
  Other brands of paper, which claim they can be used with all brands of ink jet printers, may not be compatible with the EPSON dye based inks. These papers may give you lower quality color images and will not have the longevity of EPSON's long lasting media. The ink also may not dry properly, because the ink doesn't bind properly to the media, causing smearing and pages sticking together.
