Can I select a print resolution by indicating a specific dpi (dots per inch) setting?

Note: The information below applies only to the Standard Epson printer software.
The Quality and Paper Type settings determine the print resolution.
The Media Type and Print Quality settings determine the print resolution.
Note: To access the resolution settings in OS X, select Print from the File menu. Then select Print Settings from the pop-up menu.
