I am satya from Delhi India and I have one canon all in one canon printer since 4 yeara but I there is no problem related to its quality.
Its quality is much better than other printer but its major disadvantages is only that the printer cartridges is very very expensive and the cost of printer cartridges is equal to the price of new printer.then its better to purchase new printer and sell out old printer but this process is very difficult to process then its better to purchase those printer which cartridges prices have normal rate or in the budget then those printer are best.Like Hp printers
