P1394> Native SBP-2 Printer Profile?

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.  :-)
