SystemRecommended Remote Site and LPA Properties

For optimal performance and reliability under consistent print loads, Loftware recommends setting the following Remote Site properties and system properties for the Loftware Print Agent (LPA).

Remote Site Properties

  1. Sign in to Loftware Enterprise SP on the on the initial Loftware Application Server.
  2. In Devices Devices, open the Remote Site you want to configure properties for.
  3. Click Manage Properties and update the following properties:

    Property

    Value

    CloseNetworkPrinterSocketAfterTimeout

    60000

    DeviceConnectionTimesSaveInterval

    600

    DevicePingConnectTimeout

    1000

    DevicePingRefreshInterval

    60

    DevicePingRefreshThreadsLimit

    1

    DevicePingSocketPoolDelay

    50

    LogRetentionHourOrDay

    Day

    MaximumCompoundTraceSize

    10240

    MaximumNumberOfWebSocketConnections20

    PrintDataCleanUpInterval

    120000

    PrintThreadRetentionTimeInSeconds

    60

    SendingDataToNetworkPrinterTimeout

    -1

    TraceFilterValues

    ServerCommunication,
    DeviceCommunication,
    Processing,
    JsonServerCommunication

    WaitForFINPacketWhenClosingTheConnectionToNetworkPrintertrue

    4. Note: For more consistent printing results, consider increasing the number of always-active PRNT connections using the MinimumNumberOfWebSocketConnections property. Loftware tested this feature with the default value of 1. In rare instances, a print job could be delayed if Loftware Enterprise SP tries to reuse a dropped PRNT connection. Setting this value to 2 or 3 could help prevent such delays.

  4. Save the Remote Site.
  5. Repeat the steps above for each Remote Site.

LPA System Properties

Note: To perform this task, you must be signed in as the SuperAdmin user. For more information, see the Loftware Enterprise SP User Guide (Help).

Sign in to Loftware Enterprise SP on the initial Loftware Application Server and add or update the following system properties in System > System Properties.

The namespace for all properties is lpa.

Property and Description Value
connection.status.timeout.ms

Time between scheduled process to check for connections that are never registered and clean them up. Add 2500ms to this time for when it is purged.

10000
connection.status.validation.window.ms

Timeframe in which the LPA connection is considered valid since last check. Will not check again until last checked falls outside this window.

90000
response.timeout.ms

Amount of time to wait before retrying a lookup for a response message.

30000
print.terminal.status.retries

The number of retries to attempt sending a print stream to the LPA before giving up and going into the retry loop. The default value is 10.

3
installer.file

The location to pull the download for the LPA installation.

downloads/
LoftwarePrintAgent.exe
device.ping.status.bypass

Specifies whether to perform the ping action - true means bypass and do not send.

true
device.ping.printjob.bypass

Specifies whether to perform the ping action - true means bypass and do not send.

true
device.ping.connection.prnt

Determines whether to perform a ping on connect - true means perform the ping.

true
last.contact.update.interval.millis

Periodic update of LPA connection status events from various LPA's during this timeframe.

10000
sticky.device.enabled

Override the LPA from moving the devices on connectivity. Use the manual settings for the device service JVM settings. If you change the value of this property, you must restart the Loftware Spectrum service for the change to take effect.

true
sticky.device.response.timeout.padding.ms

Granite Timeout setting for cross JVM printing.
