I have an Epson Photo 870 that works perfectly with ulpt. Well, almost. The little program that lets you detect ink levels fails, since ulpt doesn't support a back channel. But printing is flawless. The only complaint I have is that the data set for printing a single page is HUGE on this printer, and ghostscript takes a long(er) time to chew over it. But the output is so beautiful I can't complain too much. I used to have an HP DeskJet 812C. It didn't work -- it was prone to what was clearly buffer overruns within the printer. If I added delays to the ulpt driver, it worked, but then it printed extremely slowly. I figure the Windows driver must have some sort of workaround for this issue. But then lately HP has been going the undocumented-windows-only-*nix-users-can-go-suck-eggs route anyhow, so I really have no further use for them.
