Remote host

[Anonymous]

Hi,
I have a problem with cups.
I can send single files to printer but I can't send multiple files.If I send more than one file; printer prints first file but it doesn't print other files.I looked in /var/log/cups/error_log.
The error is like that:

 I [11/Aug/2005:11:38:04 +0300] Started backend
 /usr/lib/cups/backend/lpd (PID 21189) for job 169.
 W [11/Aug/2005:11:38:04 +0300] [Job 169] Remote host
 did not respond with command status byte after 300
 seconds!

Can anybody help me????????
