In a general sense, yes.  Any halfway modern Epson inkjet (that
supports ESC/P2, at any rate) does.  Gutenprint has a limit of
1200', but that's a soft limit.  The firmware-based limit is higher,
but I'd have to calculate it out.

Yes.

Don't understand the question.  Not all printers have roll feed per
se, but you can sort of fake it by pre-cutting to the right size
yourself.  Printers that don't support roll feed don't have built-in
cutters, so when it comes time to eject the paper they have to keep
ejecting until they run out of paper.

Not sure what you mean by that.

The Gutenprint core doesn't support that, and that's not the right
place for it.  That's something that should be done by the
application, although one could certainly build an image printer
application that does that.  PhotoPrint, which I'm not sure is active
any longer, could do that IIRC.
