In particular the amount of sharpening can only be critically adjusted at the final print size. To get best results (and part of "best" is "expected", meaning it is what you thought it would be), resample your photographs to 360 pixels per inch (or 720 if you wish, but it won't make a visible difference), and make all final edits at that size. With most photographs you simply cannot see the difference, but with line drawing or text it is relatively better to print at 720 pixel per inch. No matter what image data you send to the printer it prints at either 360 or 720 pixels per inch. But the lines are made up of single pixel rows, and for all practical purposes the line uses a "nearest neighbor" algorithm to convert image pixels to a dithered dot pattern in the line that is printed. The printer actually prints in whole lines, not pixels. Didn't know if 720dpi would use much more ink than 360. I was just told that it's best to keep your source resolution equal to (or in equal incremental values) of the printer's native resolution (hence the 180ppi being an incremental value of 360 or 720 or 1440). Please notice the ONE option regarding "Finest Details" which is referring to using 720 when this is selected. Then, you should be able to select your desired 360. Example, for Epson Matte Paper - there are 3 options 3, 4, or 5 which list the applicable resolution. The options will depend on the Media you have selected.

In the 3880 Printer Setup screen, check the option regarding "Print Quality" click the down v symbol, and select "Quality Options" and use the slider at the top to select the desired Quality. If you really want 360 dpi, then I think the only way to get it is to select Plain Paper and the Draft mode. Are you running the Epson Printer Watcher utility that came with the printer? It will show you how much ink is used on each print, although it is only accurate to the nearest 0.01 ml. I really doubt you will save much ink by printing at 360 dpi instead of 720 dpi. Am I missing something very obvious here? I have to change media to a matte format to be able to access lower quality settings than 720dpi.
#Epson 3880 printer dpi for matte paper driver
However, in the driver utilities, whenever I select Epson Premium Glossy photo paper as my media (which I'm using), I cannot change the print resolution below 720dpi. However, all of my files are setup at 180PPI, and I really only need the printer to be set to 360dpi, not 720 (trying to conserve ink on these large print runs).

I have my color management the way I want, and prints are matching up very well for having an uncalibrated screen. Alright, just received my Epson 3880, and I'm going to actually start printing some vector work first (exported Illustrator work in PS).
