cups printing error

Hi All,

Having searched for a solution to this issue i found no suggestions which help my particular problem.

I am getting the following error message on 1 of the 3 printers i have configured:

recoverable: Network host 'xxx.xxx.xxx.xxx' is busy; will retry in 30 seconds

All 3 printers are configured in the same way, socket://printername:9100, using the same ppd file (generic text-only), they are the same make/model (OKI 320). The only difference i can see is that they have different IP addresses.

2 of the printers work fine, it is only 1 of them that is saying it is busy.

Can anyone suggest a reason why this may be happening?

lpq -Pprinter1
printer1 is ready
no entries
lpq -Pprinter2
printer2 is ready
no entries
lpq -Pprinter3
printer3 is ready
no entries

I have checked all log directories /var/log/messages /var/log/cups/access_log and error_log and i can see no reason why printer1 is not working yet printer2 and printer3 work no problem.

Version of cups is cups.x86_64 1:1.3.7-30.el5

Thanks.
