They are not impressive but at least adequate for home use.
The most unimpressive feature of the Epson CX5500 is probably its print speed.
The speed is much worse at normal quality.

It slows down to around 2.8 ppm.
As expected, printing text with graphics takes even longer to finish.
Print quality is as almost as disappointing as print speed.

But, sometimes the printer fails to reproduce graphics accurately.
It can scan pages up to A4 size.
Mono scan speed is 4 milliseconds per line at 300 dpi and 5 milliseconds per line at 600 dpi.

Color scan speed is 12 milliseconds per line at 300 dpi and 15 milliseconds per line at 600 dpi.
The overall speed is quite slow, but it is still at an acceptable level for home users.
Anyone who needs more speed should look for a more expensive multifunction printer.
