The HP 45 black ink cartridge is used by itself in a number of monochrome Hewlett Packard printers.
Some printers that use this cartridge also use the HP 44 or HP 50 cartridges. we regret that we are unable to supply either of these cartridges
We can supply both HP original inkjet cartridges, in light user and high yield versions, and remanufactured (recycled) ink cartridges. An InkTec ink refill kit is also available, as is bulk ink for use with the kit. We do not supply compatible cartridges for this cartridge.
If you are looking for cheap ink, we recommend that you look at the prices of the cost of refilling your own ink cartridges.
