The delays appear to be hard-coded in the backend; naturally, the standard backends need to be conservative in their timing, but we'd like to be able to tune the timing for our particular printer. I don't think it has to do with the SNMP request, but I'll experiment with that to be sure.

Your SNMP fix actually makes a significant difference - instead of about 8 seconds between jobs, now it's more like 5. That's still more than we'd prefer, but it may be adequate. I don't know if I'll be able to get authorization to do a more in-depth analysis, but if I do, I'll feed the data back to you.

Thanks very much for your help,
