Epson L121 is aimed at people who only need traditional print-related features.
In other words, it is a single function printer.
Its cartridge-free ink supply system offers larger ink capacity and affordable printing.

Epson L121 is one of the many ecotank printers that Epson has developed to tackle the cost issue.
Its not the printer price that is cheaper, but the ink bottle price.
The cheap printing is not the only benefit of buying an ecotank printer like Epson L121.

The ink tank is designed to hold a massive amount of ink.
As for the output tray, it can only hold up to 30 sheets at one time.
The position of the ink tank could be considered less than satisfactory.

The ink refilling, however, is easy to do.
The designs of the ink bottles and ink tank make it so easy to do the refills.
Just plug the bottle into the tank and wait until it is full.
There is no need to squeeze the bottle.
The ink reservoir and the ease of refilling it are the other attractive aspects of the printer.
The main benefit of owning this printer, however, is its more affordable printing cost.
