Namespace: Zebra.Sdk.Printer.Discovery
Assembly: SdkApi_Core (in SdkApi_Core.dll) Version: 2.14.1989

Syntax

public static void Multicast(
	DiscoveryHandler discoveryHandler,
	int hops
)

Public Shared Sub Multicast ( 
	discoveryHandler As DiscoveryHandler,
	hops As Integer
)

public:
static void Multicast(
	DiscoveryHandler^ discoveryHandler, 
	int hops
)

Parameters

discoveryHandler: Type: Zebra.Sdk.Printer.DiscoveryDiscoveryHandler
A DiscoveryHandler instance that is used to handle discovery events (e.g. found a printer, errors, discovery finished).
hops: Type: SystemInt32
The number of hops.

Exceptions

Exception	Condition
DiscoveryException	If an error occurs while starting the discovery (errors during discovery will be sent via DiscoveryError(String).

Remarks

This method will invoke the FoundPrinter(DiscoveredPrinter) method for each printer that is found during discovery. DiscoveryFinished will be invoked when the discovery is finished and DiscoveryError(String) will be invoked when any errors are encountered during discovery. When DiscoveryError(String) is invoked, the discovery will be canceled and DiscoveryFinished will not be invoked.

If a printer responds to the discovery request more than once, the FoundPrinter(DiscoveredPrinter) method will only be invoked on the first occurrence.

For Android users : some extra code is required to obtain a multicast lock. See the example in Multicast(DiscoveryHandler, Int32, Int32)
