For most people running to the mall/office store when they need to print is a better deal. Yes the costs per page are high, but how often do you really print - between ink going dry, and cheap printers not having a long lifespan, the actual cost per page of a printer you own is probably a lot higher than you think. Plus keeping paper in the printer, and all the other issues are not your problem.
I still own my own laser printer because the convenience of not having to leave when I want to print is worth it, but I'm not pretending this is something worth doing.
