A generic cartridge shouldn't damage your printer, but it will give you less picture quality. I know it's pricey, but I suggest going for the brand name.

Cartridges compatible with the HP LaserJet P2015DN are the HP-Q7553A and HP-Q7553X (the normal and high capacity cartridges). Not made by HP, the VTQ7553A and VTQ7553X are also advertised as fitting the printer.

If you really mean a laser printer (page printer), the easiest part is the Toner Cartridge. It is made to be replaceable by the end user. If what you meant was an Ink Jet Printer (character printer), then it would be the Ink Cartridges, for the same reason.

Laser printers are not made to print quality photos. This is because the colors in powder form do not blend as well as the liquid color in inkjet cartridges. You also can't use photo paper in laser printers because the printer will melt it.
You cannot use an HP ink cartridge in a Canon printer because cartridges are made for certain printers. You have to use an HP cartridge in an HP printer and a Canon cartridge in a Canon printer.
