I am using this product since last four years without any brake and challenge.
It is really an exclusive product from the house of HP. It's efficiency is superb, it's speed is owesom for small business. It usage is very simple and operations are easiest one.
You can photo copy any A4 size with good clarity and low cost of operation. Ink cartridge is really good one and can be refilled for as low as Rs. 200 One refill last for about 2000- 3000 pages depending on how much thick printing you are doing.
Look and design is also owesom. It add value to your office or shop. Laser printing can not cheaper than at this printer.
Most important is I never faced any challenge with the product in more than four years. Still you have service center at almost every city.
