Canon PIXIMA E510 is a waste of money Valued printer. If you buy it you will realise the stupidity of yourself and the geniusness of Cannon printers because cannon have made the the printer in a way that you will have to buy only their ink cartriges and you will also need to buy a product called printer head for better printing performance.
The printer head is most important material which is just too much costlier. After all this you will have to face a software glitch which is very regular if you don’t use the printer regularly and also you will have to check the perfomace of printer every time you use it after long time which means waste of pages and colour as well as black ink. So buy smarter.
