These extra options boxes are important and can vary from printer to printer:

• Gloss - available on UltraChrome Hi-Gloss printers and activates the Gloss Optimizer cartridge
• High Speed - this activates "bi-directional" printing and can effect print quality.
• Edge Smoothing - Epson software based quality correction. Not normally recommended
• Print Preview - NOTE! If you use color profiles never choose this option. Its function is to give users a final layout "proof" but it interfers with the color management system from Photoshop.
