In general, the marketing strategy in Argentina is to import older and simpler models of tech, because they are already so expensive that the most current and fancy ones are REALLY expensive.
So when you look at the printers, or the video monitors, or the noise cancelling headphones or similar items on Mercado Libre, you will usually find models that are a generation or two behind the latest greatest stuff sold in the US or Europe.
And, since Iphones are so expensive in Argentina (usually its in the top 3 countries, worldwide, for most expensive apple products at retail) the idea of having apple specific features is not as common.
An argentine electronics wholesaler will stock the simpler cheaper stuff.
There are usually some apple compatible things, but they are harder to find and cost more.
And as I mentioned earlier, only some models means only some ink refills- Canon, for instance, is simply not stocked by most ink dealers. And fancy inks are often only at a few places, and at a premium- if you wanted the high end photo printers that use 6 colors of sublimation ink, they are not going to be cheap, and not at the corner store.
If you have very specific needs for tech, first check mercado libre and see if its even available, then, note prices. Some things it definitely makes sense to bring in checked luggage.
