cheaper printing 100 page for less than 50 cent

First I am going to tell you that if you have problems in printing after filling the cartridge ink, you can comment or ask in the video and say what is the problem, so I can help you because I discovered the secret and the way the printer works good 100%, but if you want to refill, in this video you will see how to fill an ink cartridge for an HP printer in a simple and efficient way, you will save a lot of money. In the video you can see there is a red led light, indicating that the cartridge is empty, but at the same time that the manufacturer's program detects that it is a refilling cartridge, they will always keep the light on and send you notifications that you need to buy a cartridge ink, then the problems starts and some pages go blank or half done, I discovered how to avoid that, so that the printer works 100%, is removing the software from the manufacturer, later almost at the end of the video you will see that it prints well without that red light and I will tell you what I did.
