Experience with ones that don't dry up like this?
That pretty much happens with any inkjet cartridge that doesn't get regular use. (It doesn't have to be
heavy use, just
regular.)
Any suggestions for an inexpensive low volume printer?
If you have a strong preference for staying with an inkjet, I'd suggest getting in the habit of printing a short "refresh" document designed to hit all the cartridges every few days (or perhaps even setting up an auto-scheduled task to do it). It doesn't have to be much - even a one pager with relatively little printing should do it; you just need to keep the ink at the surface of the heads from getting too hard-dry...
Or just get an inexpensive monochrome laser printer (decent ones can be as cheap as $60-70 on sale) and "outsource" your color work. Photo-printing is pretty readily available at a lot of places and you could do color document printing at a place like Staples, Kinko's, or a local shop. Since you apparently do it so infrequently, it seems like that shouldn't be too big a PITA. (And though I don't do it myself so I'm not sure, I think the big, and maybe most small, places let you submit print jobs over the Web, so you just have to swing by to pick it up, rather than actually having to sit and do it all there.)
You can get
relatively inexpensive color laser printers, too, but the cheap ones don't produce great quality printing, and the better ones are pretty expensive (and the toner ain't cheap either, though at least it won't dry up on you.) Inexpensive monochrome printers on the other hand have good basic print quality. What you don't get in an inexpensive B&W laser is one that has lots of bells and whistles, or that can handle large-format printing, or high volume.
