Epson Stylus COLOR 670 Daily Use page 38

Using the Automatic mode
When Automatic is selected as the Mode setting in the Print dialog
box, the printer driver takes care of all detailed settings based on
the current Media Type and Ink settings. To make the Ink setting,
click Color to print in color, or Black to print in black-and-white
or grayscale. To make the Media Type setting, see "Making the
Media Type setting" on page 28.
Note:
Depending on the media you choose in the Media Type list (while
Automatic is selected), a slider appears to the right of the Mode options
that lets you choose Quality or Speed. Select Quality when print
quality is more important than speed.
Using the PhotoEnhance mode
The Photo Enhance mode provides a variety of image-correction
settings that you can apply to your photo images before printing.
PhotoEnhance does not affect your original data.
