We have a HP 470wt with a 12volt plug
, small and unobtrusive, and with the wireless feature can print anywhere within 100 meters of the boat when we turn it on.
Unfortunately it rarely gets turned on and the cartridges dry out. I give them a sitzbath in a saucer filled with warm water
and then wipe with soft cloth. If it's real bad I'll blow on the vent to unplug.
Given how infrequently we use the printer; toss in the hassle-factor of plugged cartridges; while I'm not read to get rid of it, I'm not sure it's worth the 'convenience'.
