This is not enough output resolution for a high quality print, as we'll see below."
Basically, the threshold of minimum resolution (and this depends on the printer) is somewhere between say 180ppi and 200ppi. Of course you can use less pixels per inch but quality suffers. In the very, very old days (1992 or so) the very first contone printer I used was a Kodak XL-7700 dye sub. It had an output rez of 203dpi (you sent it 203ppi). Back then, that was still a big file for a 10x10 print. Why 203? Well Kodak found that was close to the minimum data needed to make a good print. Today, with a decent ink jet like an Epson, you can get away with 180ppi and at viewing distance, it will look fine.
At 155 ppi, the document's width is 14".
I get 13.9 so our math is damn close. Typo?
