Change the polling time for Print Deploy

This page applies to:

The polling frequency determines how often the Print Deploy client contacts the Application Server to check for new print queues. By default, this is every 15 minutes plus and minus a random offset to avoid all clients calling in at the same time.

The Print Deploy client polls the server for a list of printers every x number of seconds, where:

x =IntervalSecs + Rand.between(MinRandomOffsetSecs , MaxRandomOffsetSecs)

Changing the polling values

You can change the number of seconds in two ways:

  • Via the Settings tab in the Print Deploy admin interface.

  • Update the values in the client.conf.toml file, located in:

    <PaperCut NG\MF installation folder>\providers\print-deploy\win\data\config\client.conf.toml

    Any change to the .toml file requires a PaperCut Print Deploy Server service restart .

The config values that change the polling frequency are:

[PollingConfig]
IntervalSecs = 900
MinRandomOffsetSecs = -300
MaxRandomOffsetSecs = 300

As an example of how the values work, the polling values above give a polling time of 15 minutes, plus or minus 5 minutes. This results in a minimum time of 10 minutes and maximum time of 20 minutes. They are calculated after each check-in.

Config value 
IntervalSecsA positive integer value.
Default is 900 seconds.
MinRandomOffsetSecsAn integer value lesser than or equal to MaxRandomOffsetSecs.
This value should be negative.
Defaults to -300 seconds.
Minimum value: -2147483647 (This value should not exceed the intervalSecs value.)
MaxRandomOffsetSecsMust be a positive value.
Defaults to 300 seconds.
Maximum value: 2147483647

You can confirm your configuration on the user’s computer by looking at the following logs:

Windows: C:\Program Files\PaperCut Print Deploy Client\data\logs\pc-print-deploy-client.log

macOS: /Applications/PaperCut Print Deploy Client/data/logs/pc-print-deploy-client.log

The PaperCutPrint Deploy Client logs look like this:
