Specifies how often InfoPrint computes the queue backlog.
Backlog update interval
You can enter a value using [HH:]MM. The unit is minutes or hours and minutes, separated by a colon.
Setting this value to 0 disables backlog computing.
The greater value of:
- 1 minute
- The value of the backlog-upper-bound attribute divided by 30.
- This attribute is only valid when the queue-type attribute is set to standard-queue.
- You must set the value for this attribute to be less than or equal to the value you specify for the backlog-upper-bound attribute.
- InfoPrint sets this default value when you create the queue. If you change the value for the backlog-upper-bound attribute later with the pdset command, InfoPrint does not change the value for this attribute.
