Data Query Speed

The data query speed dialog box controls the manner in which QView Pro gathers data for each print job in all displayed print queues. The amount of data that QView Pro will need to gather depends on the number of print queue windows open, and the number of jobs in each queue.

Query Cycle This option controls the frequency at which QView Pro refreshes information about each print job. The default is to update all information once every 2.0 seconds. You can increase this to query faster (once a second) or slow the process down so the data is updated only once every 30 seconds. The amount of information QView gathers is static. This option only controls the speed at which QView queries the file servers for the information. Slow data gathering leads to inaccurate information on the QView Pro display. Fast data gathering taxes the server and creates excessive network traffic.

Stop when minimized When checked, this allows QView to stop querying the print queues while it is minimized (iconized). If you have any automatic job scanning features enabled such as Duplicate Scanning, QView will not scan while minimized. This feature is good for users who only view and manually control the print queues. If you need to scan queues while QView is minimized, uncheck this option. This feature does not affect individual queue windows that are minimized. It only applies to the main QView Pro application window.

Stagger data queries This option spreads the data requests to make even use of the Query Cycle time. If this option is not checked, QView will gather information about each print job as fast as possible once every cycle. If it is enabled, QView will pause between each data request to evenly spread the work over the total Query Cycle. While running with this option off, you may notice your machine pause once every few seconds while QView gathers data.

Network Traffic created by QView Pro If you have dozens of queue windows open each with tens of jobs, you may begin to affect network bandwidth. If you are concerned about network traffic, try to minimize the number of windows you have open concurrently and increase the Query Cycle so the traffic is spread out over a longer period of time. Each open window creates approximately 10 packets per Query Cycle, and each print job creates approximately 4 packets. CRC Checking for duplicates greatly increases network traffic because QView reads the entire print job data file to calculate a checksum for the job.
