Hi. I have a Centos 6 server that use CUPS to print invoices, quotes, etc, but whe the ADSL get down the CUPS server stop connecting to the printers via LPD.
The ADSL gateway is a Cisco 800 series router provided by the ISP. The router is on and reachable but if no ADSL no printing.
What will be happening in the back? Centos 5 has a similar problem, but it prints, slow but prints.
