ControllerPort

integer

5555

DesktopInterfacePort

integer

5558

Port number on which Desktop Interface connects to FlexiSpooler

SpoolerId

Guid

new Guid

Unique FlexiSpooler identification for Spooler Controllers, it should not change for the entire lifetime of a FlexiSpooler (that is why IP/host cannot be used). If not filled, it will be filled by a new GUID upon the first start of FlexiSpooler. Do not change this option! Spooler Controllers store the SpoolerId in their metadata for each received job, changing it would mean losing access to all jobs previously stored by that FlexiSpooler.

UiId

string

SpoolerId-ClientUi

Similar as SpoolerId, this is Desktop Interface's static unique identification and is derived from SpoolerId upon the first run, do not change this option!

ConnectionLostTimeout

TimeSpan

0:1:0

FlexiSpooler uses heartbeat to check the availability of its Spooler Controller, if it is unresponsive for the specified time (1 minute by default), FlexiSpooler can react, failover to another Spooler Controller, go to offline print mode, etc. A higher value may be needed for networks with a high latency or for performance reasons.

uiLaunchCheckInterval

integer

-1

Desktop Interface must be running in every user's session for the users to be able to submit print jobs. This property activates automatic checking of the presence of Desktop Interface in all user sessions on the workstation and it starts a new instance when it detects a session without Desktop Interface. The checking is disabled by default. The value of the property specifies an interval in minutes and how often the check is executed.

CertificateThumbprint

string

empty string

If left empty, plain communication is used. Otherwise, FlexiSpooler will look for a matching certificate signed by a trusted authority and use it to authenticate itself to Spooler Controllers (and it will negotiate encryption with it). It will also communicate securely with Desktop Interface. The "encryption" (from MU14) variable must also be set.

encryption

(from MU14)

string

 Plain

Encryption key lengths:

Supported values are (case insensitive):

• Plain
• Aes128

CertificateStore

enum

My

For secure communication, FlexiSpooler needs a certificate to authenticate itself. It looks for it in the Windows certificate store specified by this option (Personal store by default).

ValidateServerCertificateHost

boolean

true

By default when authenticating a Spooler Controller, FlexiSpooler also checks if one of the IPs/hosts in the Spooler Controller certificate's subject alternate name matches its IP/host. It's not recommended to turn off this option.

ListeningOnAddress

string

0.0.0.0

Address on which FlexiSpooler listens for HTTP(s) connections. By default, it listens to all IPv4 addresses on the local machine.

ListeningForJobsOnAddress

string

0.0.0.0

Address on which FlexiSpooler listens for LPR connections. By default, it listens to all IPv4 addresses on the local machine.

SpoolerPort

integer

5559

Port number on which FlexiSpooler listens for http(s) connections.

HttpRequestTimeout

TimeSpan

0:10:0

Timeout for HTTP requests, default is 10 minutes. Non-spooling client FlexiSpoolers transfer job data to spooling server FlexiSpoolers via HTTP, which can take a while depending on job size and network speed, if these transfers fail due to timeout, a higher value might be necessary.

HttpCompression

boolean

true

When true, FlexiSpooler uses GZip to compress its HTTP requests, to transfer jobs faster and save network bandwidth.

IgnoreCertificateChainError

boolean

true

This allows a self-signed certificate to be used on the server FlexiSpooler for HTTPS authentication, if true, the certificate chain is ignored during validation.

MaxHttpConnections

int

100

The limit for outgoing HTTP connections on the client side.

ServerSpoolerAddresses

array of strings

empty array

This enables failover and virtual IPs for non-spooling servers (see FlexiSpooler Modes). Non-spooling client FlexiSpoolers ask their server FlexiSpooler for addresses of all server FlexiSpoolers, so they can failover when one server is down. Spooling server FlexiSpoolers are always on the same server as Spooler Controllers, so they just return the IPs of their Spooler Controller Group. But a non-spooling server returns only its own IP addresses (the "real" ones from network interfaces). When this option is filled, the non-spooling server returns its value instead. This solves a scenario when the non-spooling server is only accessible through a public virtual IP address different from its real IP(for example a server in Azure cloud). It also gives administrators the option to manually configure a non-spooling server FlexiSpooler cluster for failover.

HttpAuthenticationMethod

None/AzureActiveDirectory

None

This allows client authentication for https communication via Azure Active Directory(server authentication is done via certificates). To use AAD, more local configuration options are necessary - AzureActiveDirectoryTenant, AzureActiveDirectoryAuthorizationEndpoint, AzureApplicationIdUri and AzureNativeClientId. More details are in FlexiSpooler Server HTTP authentication configuration - Azure AD.

ServerDiscoveryEnabled

boolean

true

Configuration for DHCP discovery. When true, FlexiSpooler queries the DHCP server for option 9 information.
Value can be overwritten in spooler.config file, to disable it set "ServerDiscoveryEnabled": "False". For disabling it in the silent installer use parameter /CFG:noServerDiscovery.

spoolerUpdateCheckIntervalInMinutes

integer

4

Intervals in which FlexiSpooler checks for a new version, default is 4 minutes.

updateServerHttpPort

integer

443

Port number on which FlexiSpooler connects to Update Server.

culture

string

If set, this forces different culture on Desktop Interface (and localize its string in a different language) than the current culture on that machine. Example "en-US", all codes are here: https://msdn.microsoft.com/en-us/library/ee825488(v=cs.20).aspx

processingTimeWithoutNotification

integer

5000

When receiving a job, FlexiSpooler needs to process it, if it takes longer than this time (5 seconds by default), Desktop Interface will display a notification to inform the user. Setting this to 0 means that a notification will always be displayed after each job.

authenticationType

            string

DOMAIN_USERNAME

DOMAIN_USERNAME

When set to Domain username, the username of the user logged into the workstation is used.

USERNAME_AND_PASSWORD

When set to Username and password, the user will be prompted for a username and password.

STORED_USERNAME

USERNAME

When set to Username, the user will be prompted only for a username.

CARD

When set to Card, the user will be prompted to swipe their card.

PIN

When set to PIN, the user will be prompted for a PIN.
