Hi, Sun Managers:
    At first, thanks all people who give me sugestion and information.
    I received message from our mail daemon: can't send this message to
    sun_manager list, so I resend it once. If this message is duplicated,
    please ignore it.
    I got many answers, and summary it as follows:
I. from David Beard<beard@abel.maths.adelaide.edu.au>
    Try something like
        # ps waux | grep daemon
    and kill -9 any processes connected with newsprint, e.g.
        /usr/newsprint/small_openwin/bin/xnews -cubesize large
    You might then need to do a "lpc restart".  Either or both of these 
    things fixes our printer most of the time.
II. from Raimondo Ballisti<ballisti@ifh.ee.ethz.ch>
    1) You have to be root and "abort" and "start" the printer from lpc.
    2) If this does not help, then you can reload the driver.
III. from Ricardo J Ruiz<rruiz@Census.GOV>
    You need to reboot the system.  I think there is a jumbo patch for lpr 
    that should take care of this problem.
IV. from <bismark@alta.jpl.nasa.gov>
    % lpc down all
    % kill -9 lp_daemon_pid
    % /usr/lib/lpd
    % lpc up all
V. from <uthke@ite.iabg.de>
    Call lpc and then try
     
    down <printername>
    up <printername>
    restart <printername>
     
    This helped in our case.
VI. from Peter Allan<pallan@clare.risley.aeat.co.uk>
    lpc start seems more powerful than restart.
    Removing the top queued job may help.
    Also you could kill the lpc daemon & restart it.
If I loss any people, I am sorry.
