Pelagic-
Buried in the sales
sheets, for every printer there is a "duty cycle" rated in pages per month. I'm not sure who is using what numbers, but basically if you take that number of ppm times 60 months, five years, that's the lifetime you might expect before the whole printer can be tossed. None of them are "durable goods" any more. And unless you move from "home" to "office" category, they can have surprisingly low page counts. Which still might be more than a boat really needs.
Color lasers generally have 4 totally separate imaging stations, making them 4 times more complex than b&w laser printers. Generally an expense (buying 4 sets of imaging drums at $100? each) that smaller users wouldn't want to carry.
But the "tropics" in general, with higher humidity, would be good for inkjets, and that same humidity literally dissipates the static charge that lasers rely on to create the image. (On older models, it also lead to a gray background as the toner migrated everywhere.)
If you can find a machine from a vendor that does not require proprietary "chipped" cartridges, there's at least a chance you can find refilling in many places. The colors won't compete with Epson or other quality
photo printers...but at least they can print.
I got a rude surprise from a well-rated Brother "office" inkjet. The colors are a very inferior mix, compared to an ordinary HP printer. But, the HP costs more to feed, and their
reliability just isn't there. (This one needs a new circuit board, which costs substantially more than the printer did.)
Also beware of any model with a proven track
record, because if it is five years old? Right, the maker will be discontinuing it soon, to replace it with something new. And that means no more ink cartridges. Make sure that whatever you get, it takes cartridges commonly found in office supply or discount stores, or available from third parties.
Third party ink *may* damage printheads, usually that's FUD. Some printers actually have a printhead ON the ink cartridge, so it is replaced whenever you change ink. Others, like (most? all?) the HP's, have the heads separate in the printer.
Bottom line, the printers these days are all like fruit, they will
rot on the shelf and have to be replaced from time to time. Not the durable goods that they used to be.
Oh, and from HP: The cartridges, new, unopened, sealed spares? Also need to be stored "this side up" so that any pigment which does settle out and clog, won't clog the cartridge. Who knew?
