Something to keep in mind when selecting a printer with refillable
liquid ink tanks is that they all have an internal waste ink
repository, which is a sponge that soaks up unused ink that apparently
accrues slowly through normal use, or quicker any time you do an ink
purge [1]. On very high end photo printers it's replaceable, and might
be described as a maintenance cartridge in the specs. If it fills up
and can't be replaced, the printer is dead. When I was shopping
around, the only brand I could find that had replaceable waste ink
repositories even at the low end was Canon, and being too cheap even
to have a network interface also saved me the trouble of firewalling
it.
It's true that ink tank printers need to be used regularly or else the print heads dry out like a felt tip pen. Since the ink costs next to nothing per page, I print a full page family photo once a week and hang it up somewhere around the house if I haven't used the printer for anything else, which still works out cheaper than any alternatives. The walls look like instagram, but being reminded of loved ones might not be such a bad thing.
