Interresting thoughts, though the PWG is not trying to create
a truly native SBP-2 printer profile. As I think about it, I
don't know of _anyone_ that is.

Your thoughts imply that:

- a truly native SBP-2 printer profile has a standard "printer"
device model with standardized status info.

- the printer is being driven by an intelligent agent which is
aware of command boundaries. So it's either driven directly
by the printer driver, or by a command-set-intelligent spooler.

By the way, I don't want my printer to throw away the rest of
the data when it runs out of paper. I want it to tell me it's
out of paper, wait for me to put paper in, and then continue
printing. :-)
