    1. All producers are irrelevant in the market
    2. All consumers have perfect knowledge of the market
    3. There is only one market

This simply means that capitalism is achievable only as an approximation, how good depends on the people who set the rules.

    In the case of printer cartridges, 1 goes bananas because every producer is a near-monopolist of his printers; 2 goes bananas because few know that it is possible to hack printers to pay less; and 3 because every printer manufacturer has his cartridge market, sometimes more as their printers are normally not cross-compatible.

Electronics has to be able to direct correct amount of ink at the right time.

The result is very nice solid blocks of pure colour, but it's obviously a precision process which needs the wax to stay at exactly the right consistency for exactly the right length of time at a particular temperature. It's easy to imagine that another company trying to replicate the Tektronix wax formula would end up with something very nearly the same, but it will almost certainly solidify very slightly more quickly - or very slightly more slowly - than the official shizzle, increasing the risk of congealed wax ending up in unwanted places and clogging the mechanism.

It is much worse on the C80/82/84's however. Those had quite a bit of ink left, enough so that when I reset the chip, it was able to print about 200 or more pages after it claimed it was empty. The 800/825/925, however, had enough for a few pages at best due to evaporative losses. If you want to play around with yield comparisons, this device is available in a few places which you can find on goodle.

    Take it out for more than 30 seconds.

    Then the printer will report it "full". Read your owners manual for more information.

    Most epsons I've used do not interface with the cartridge whatsoever -- at least the older ones.

    At PCworld, they have an article explaining this exact issue.

    I only mention it because I'm in it :)
