The Epson EcoTank
Expression ET-2550 is part of the
Printers test program at
Consumer Reports. In our lab tests, Printers--All-in-one
models like the Expression ET-2550 are rated on multiple criteria, such as those
listed below.
Text quality
This indicates how crisply and clearly a printer produced black text in a variety of faces, sizes, and styles. Models with higher scores produce more uniform type, with sharper edges and smoother curves.
Text speed
This score reflects how quickly the model can print text on five pages of plain, letter-sized pages. 30 seconds or less is excellent; 31 to 60 seconds is very good; 61 to 90 seconds is good; 91 to 120 seconds is fair; and longer than 120 seconds is poor.
Graphics quality
Our assessment of the appearance of color graphics produced by the printer. Black and white lasers were judged on black and white graphics.
