Make sure you purchase the right ink cartridges for your specific printer and printer region or have your old ones refilled. Cartridges are not compatible between different brands, and often not within the same brand. HP often designs its inkjet hardware to use country-specific consumables. When you unbox a new HP inkjet printer and set it up, you install a set of ink tanks that ship with the printer. As you turn on the device and get ready to use it, an initialization sequence localizes it to the country associated with the ink cartridges you installed.
HP recommends that you use original HP ink cartridges. XL (Extra Large) cartridges cost more but do provide better value in the long run. They will be able to print at least double the pages of a regular cartridge. Our advice is that if you print often, go with XL. However, ink can dry up. So if you are not a frequent printer, go with the regular cartridges.
Ink level warnings and indicators provide estimates for planning purposes only. When you receive a low-ink warning message, consider having a replacement cartridge available to avoid possible printing delays. You do not have to replace the cartridges until the print quality is unacceptable. You’ll usually install both the black and tri-color cartridges in the HP Deskjet, however, you can use the single-cartridge mode to operate the HP All-in-One with only one print cartridge. The single-cartridge mode is initiated when a print cartridge is removed from the ink cartridge carriage. During single-cartridge mode, the printer can copy documents, copy photos, and print jobs from the computer.
For your US HP Deskjet 2548 Printer you need
HP 61 or HP 61XL cartridges.
For your European or UK HP Deskjet 2548 Printer you need HP 301 or HP 301XL cartridges.

Replace the ink cartridges
2. Load unused, plain white letter or A4-sized paper in the tray, if you have not already done so.
4. Press down on the cartridge to release it, and then pull it toward you out its slot. Remove the cartridge from the slot on the left to replace the color cartridge. Remove the cartridge from the slot on the right to replace the black cartridge.
7. Hold the cartridge by its sides with the nozzles toward the printer, and then insert the cartridge into its slot. Make sure that the cartridge is inserted in the correct slot. The tri-color cartridge goes in the slot on the left. The black cartridge goes in the slot on the right. Push the cartridge forward into its slot until it snaps into place.
