Feature: processing priority
Section Variable
features priority

Values:

  • '0': No change in driver's process priority
  • '1…19': Adapt the driver's process priority to a lower priority

This entry can lower the priority of the driver. For the time of processing the print job, the driver may consume many CPU cycles, which can disturb other activity in the system. By lowering its priority this can be mitigated. The value set here is the so called nice level. Refer "man nice" for further details on it.

Note
If you don't set this feature, the default is "no change of the priority"
You can never set a higher priority this way.
