Can the ink cartridges and photo paper be purchased separately?

Sorry, you cannot buy ink cartridges and paper separately. 1 cartridge will come with 40 sheets of paper in each refill box. Each cartridge in the refill pack supports 40 prints, so you don't need to buy them separately. The set has taken into account the life of each ink cartridge and determined the amount of paper based on this, which saves you the time of ordering additional ink cartridges or paper.
