Sounds like the original poster has more than enough info, but having heavily researched this area more than once and personally dealt with printers from several manufacturers, I've got a strong opinion.
But first: Epson's drivers really do seem to have a problem with the Classic environment, don't they? My dad's Epson scanner, though it works beautifully, absolutely refuses to run from X when Classic is running, and the last time I tried to set up an Epson printer it usually wouldn't print from X once you'd printed something from Classic. The printer drivers have improved, but I was sorely disappointed.
As far as printers go, at this pint it seems to break down this way:
HP: Solid quality, reasonable prices, outrageously expensive ink, since the print heads are on the ink cartridges. But they don't clog, at least. I wouldn't buy one on account of the per-page cost (and I just don't like HP, but for different reasons).
Epson: Spectacular photo print quality, suck ink like nobody's business, and the print heads aren't easily replacable and are very prone to clogging. I've set up several, but I'd only buy one if photo quality was paramount regardless of cost and hassle.
Lexmark: Cheap, and you get what you pay for.
Canon: They *used* to be pretty lame in terms of color rendition, but the past two generations are awesome general purpose printers. Text is good, photos look very, very good if you use Canon ink and good paper, they've got good drivers, and not only do they have long-lasting individual color ink tanks, but the print head is user replaceable if it ever does clog.
Perosonally, I wouldn't even consider buying anything but a Canon inkjet at this point. I have an S750, and I've set up another; they both have reasonable ink prices, produce good text, and great photos on Canon Photo Paper Pro. I just set my dad up with an i860, and that thing is even better--gorgeous photos, and it only cost $130.
To be honest, I don't know why anybody would buy anything but a Canon these days. I wouldnt've said the same four years ago, but they're hard to beat now.
