How do I print in draft mode on Epson Workforce 3540

Question

I just bought and set up an Epson Workforce all in one printer.  Everything is working fine, except that I can't get it to print in draft mode.
I've tried a few different applications and all are the same.  When I go to print, I get a window that includes a print quality slider at the bottom that includes three settings: draft, normal, and best.  The word "draft" is grayed-out.  If I try to drag the slider to it, it snaps back to normal in the middle.
I looked in the printer's manual, and it says draft mode can only be selected with "plain paper" selected.  But, even when I have plain paper selected, I cannot choose draft quality.  In fact, it seems no matter what I try I cannot choose draft quality.
The printer's owner's manual, it also shows some printer dialog windows that I don't get (I think I did get them with the Epson I just replaced, though).
Can anyone tell me how I can select draft print quality, and why I'm having so many problems doing so?  Maybe it's to be expected that the Epson isn't letting me select the print mode quality that would save me the most ink.
I'm attaching a screen capture of what I see when I try to print.  It is the first image.
I'm also attaching a couple of screen captures from the printer's owner's manual section on Mac printing.  These are the printer dialog windows I don't see when I try to print.
What I see when I try to print (note that "Draft" is grayed-out on the quality slider):
These are what the printer's manual seems to suggest I should see (and what I think I did see with my last Epson printer that I just replaced):

Based on your screen captures I believe you may have selected Apple's AirPrint driver rather than the Epson driver. This can happen if you add the printer by selecting it from the small pop-up window that appears with a heading of Nearby Printers after you click the plus button in the Print & Scan preference pane.
To confirm which printer driver you are using, open the Print & Scan preference pane and select the Epson in the Printers colum. The right pane will give some details about the printer. If there is mention of AirPrint in the printer Name or Kind, then this will be the issue. The fix would be to remove this printer from Print & Scan and add again. But this time, don't select the Epson from the Nearby Printers pop-up. Instead, click on Add Printer Or Scanner from this pop-up window and from the next Default Add printer window, select the Epson in the list and ensure you select the Epson driver in the Use menu rather than the AirPrint driver.
