Hello,

on the [EMAIL PROTECTED] mailing list there is a user who asked
about the following issue:
----------------------------------------------------------------
I am using HP laserJet 4050 and hp4050_6.ppd driver.
...
printer is connected as socket://"ip number here":9100.
...
I would like to know the exact meaning of printer state shown in
http://localhost:631/printers. Is it the real status of printer
or is it the status of cups scheduler.
----------------------------------------------------------------

He reported that http://localhost:631/printers already shows
the state IDLE when the printer is still printing some sheets
of the last print job.

Michael Sweet answered that
----------------------------------------------------------------
... jobs are not completed until the backend exits, which can
either mean all data has been sent (most local connections) or
the printer has indicated the job has been completely printed
(most network connections).
...
it is possible that the printer has recieved all data and the
JetDirect card has been told that all pages have been processed
by the printer (but might not yet be totally printed...)
----------------------------------------------------------------

Now my question is whether the hp backend would show the really
correct state of the actual printer?

For example the hp backend might know (and report) the exact
current state of the actual printer via SNMP queries.

Could you explain the difference regarding printer state
when the generic CUPS socket or lpd backend is used
in contrast to when the HPLIP hp backend is used?


Many Thanks and Kind Regards
Johannes Meixner
