I dumped HP years ago because of the 3-in-1 cartridges and the near impossibility to unclog them.
We now have a Stylus Color Pro 1400 and before that an R360. Both will let you print until a cartridge expires. You get plenty of warning when at least one is running low and the printer will tell you which ones with a simple check.
The only downside is that the estimate is based on what the printer *thinks* remains. If you have to unclog it, that is a >10% hit against all cartridges. But then I have no idea how HP accounts for cleaning.
