Jobs going to Stopped - Cups Restart theOnly Resort

Thu Nov 4 11:55:22 PDT 2010

Dear Cups Team,

Is there a way to reduce the wait time of 300 seconds for reading the command status bytes as it appears in the logs below?

"Remote host did not respond with command status byte after 300 seconds"

What could be the lowest possible safe value that I can use for this?

Regards,
Anurag
