GUI label

Backlog update interval


Resettable, single-valued

Allowed Values

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.

Default Value

The greater value of:

  • 1 minute
  • The value of the backlog-upper-bound attribute divided by 30.

Usage Guidelines

  • 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.
