Network printer link droped

Here's my problem for the connexion gurus on the list.

I created several *LAN TCP/IP printers (ordinary &
IPDS) via CRTDEVPRT, each one with its own IP address.
All printers are HP or Lexmark, ethernet 10/100, local
or remote.

Everything is working fine ... but the writers are
dropped several times a day. The bug occurs when a
first file is to be printed, having the message :
__________________________________________________
                                                      
                       
Message ID . . . . . . :   PQT3621
Severity . . . . . . . :   40        
Message type . . . . . :   Information                
                       
                                                      
                       
Message . . . . :   The session with device xxxxx
ended abnormally.       
Cause . . . . . :   The session with device xxxxx at
RMTLOCNAME 199.202.202.43, using PORT 9100, ended
abnormally.  The error code is 20, which indicates one
of the following conditions:
20-39: A communications failure occurred.
40-59: An internal failure occurred.                  
                   
Recovery  . . . :   For error codes 20-39, check for
problems in your network. After correcting the
problem, start the printer writer ( ... )

I checked all parms, nothing seems to be wrong. The
network guys confirmed having no problem from their
part.

I extended my tests and defined remote IP OUTQs on the
same printers. They work OK and are always ON, as they
don't have any printer writer attached.

But I cannot use them in IPDS, so I return to the need
of having IP printer writers ...

When I restart the writer, all accumulated spools in
OUTQ are printed normally. But I know next time it
will behave the same and the connexion will be
dropped.

Any ideas ???

Thanks
