For photos that is probably good advice, but if you have text then 
you will want some multiple of 360ppi for an Epson printer, and I 
think 300ppi for a Canon or HP printer (Canon and HP may have changed 
since I last looked into this, so verify before taking as gospel).

Now as far as the printer resoltuion for the different quality 
settings in the driver, it's hard to tell. But best photo will 
probably be the highest (2880???) and photo probably 1440, and so on 
down the line until you get to draft which is probably 180dpi. I 
don't think the 9800 gets into the optimized 5760dpi setting that 
some of the desktop printers will claim.

Also notice that I switched between PPI (pixels per inch) from the 
paragraph about the image to DPI (dots per inch) when talking about 
what the printer can put on the paper. I didn't want anyone to think 
I had made a mistake or that the two different expressions can be 
used interchangably.
