CUPS problem

[Vu Pham]

We upgraded a server from RHEL4 to RHEL5. Everything is ok except
printing. The problem is lpstat shows the printer is idle and enable and
there are several jobs for that printers and they are never sent to the
printer.

More details: I print three files in a row, say f1, f2 and f3.

tcpdump shows that f1 is sent and the printer is printing, then f2 is
sent after f1 has been sent but before the printer finishes printing f1.
The printer returns an error code Printer busy then continue printing.

CUPS does show this error and lpstat shows " Network host
'192.168.244.52' is busy, down, or unreachable; will retry in 30
seconds..." then within 30 seconds, f2 is sent again and is printed
sucessfully.

The problem is f3 is never sent or printed. Then lpstat shows the
printer is ready, and the job just sits on the server.


Anyone experiences this problem ?

Thanks,

Vu
