You can pretty much do nothing with your HP Photosmart 6512 E-All-in-One when it runs out of ink, so make sure to always have replacement HP ink cartridges on hand. But the cost of OEM cartridges can be really expensive, so this is probably the reason why you can't easily get a spare. Good thing, there are cheaper alternatives available here at Inkjets. Our Remanufactured HP 564XL Ink Cartridges are rebuilt following strict quality control standards to ensure they meet or exceed OEM specifications but are sold at almost half the cost of OEMs. So, why wait until your Photosmart 6512 E-All-in-One runs out of ink before you get a replacement? With Inkjets' cheaper printer supplies, you won't have to hesitate to get a replacement sooner again.
