You will sometimes have better luck if you 'lpc abort' the queue,
wait a few seconds, and then 'lpc start' it.  Of course, that
doesn't solve the actual problem...
I believe that lpr/lpd is not resetting after receiving a
Busy/Ready (or Nack/Ack) signal.
Has anyone else seen this problem before?
I have not heard of it.  I'd like to see some actual proof of
what is happening (like a tcpdump) before assuming that it's
lpd's fault.  Mind you, I'm quite willing to believe it's lpd's
fault, but I can't very well look into the problem unless I know
what sequence of packets is causing it.

lpc problem with LinkSys print servers

2003-03-03 Thread Peter Elsner
Greetings hackers...

I have an interesting little problem.   I have about 13 customers that are 
running FreeBSD 4.5 to 4.7 (STABLE), with
3-port LinkSys print servers.

Everything seems to be working fine.  For the past 3 months one of these 
customers was reporting printing problems
on one of their printers connected to the print server.  The other printers 
are working just fine.  This particular printer is
a high load printer, printing about 50 to 70 pages at a 
time.  Occasionally, the printer just stops while printing.

We have to force a 'lpc restart lsjd1p2' command several times to get the 
printer to restart again.

Since it was only happening to one of the 13 sites, I attributed the 
problem to hardware... (cable, print server, printer, etc).

We have since changed out print servers, printers, cables and everything I 
could think of, all to no avail... The printer still
stops right in the middle of a print job.

Just now, another customer has reported the exact same problem.  They had a 
local hard ware tech come out
and he updated firmware on the print server, installed a new print server, 
switched out printers, and replaced cables
(both network and parallel).  Nothing has changed... The printer still 
stops while printing large print jobs.

I believe that lpr/lpd is not resetting after receiving a Busy/Ready (or 
Nack/Ack) signal.

Has anyone else seen this problem before?

Thanks in advance...

Peter Elsner

that 10 or 15 years from now, she will come to me and say Daddy, where
were you when they took freedom of the press away from the Internet?
