What I do not understand it is this: The business model of these devices is based on a yet favorable selling price of the equipment and the manufacturer is eligible on the cartridges to its profit. How can complicate only print so you then that any normal person will print as little as possible, because it is so cumbersome, prone to failure and frustrating? It would be smart to make printing as easy for the user rather like much and prints. This certainly not happened.
The supposedly low price per printed page is passed through the extremely difficult handling absurdity - after all, the printing costs will remain fairly low because hardly anyone is doing the voluntary permanently. Luckily for me this is only my second unit, because I have a working b / w laser printers and am then only rely on color printouts, but recommended the device is not natural.
If one remembers the indestructible HP inkjet earlier, this is a very sad development.
