NetworkDiscovererDirectedBroadcast Method (DiscoveryHandler, String)

Sends a directed broadcast discovery packet to the subnet specified by ipAddress.

Namespace:  Zebra.Sdk.Printer.Discovery
Assembly:  SdkApi_Core (in SdkApi_Core.dll) Version: 2.14.1989
Syntax
public static void DirectedBroadcast(
	DiscoveryHandler discoveryHandler,
	string ipAddress
)

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).
ipAddress
Type: SystemString
The IP address of the subnet.
Exceptions
ExceptionCondition
DiscoveryExceptionIf an error occurs while starting the discovery (errors during discovery will be sent via DiscoveryError(String).
Remarks
Directed broadcasts are defined by the first three subnet octets, followed by 255, such as 192.168.2.255. This method accepts IP addresses of the form, assuming a subnet of 192.168.2:
  • 192.168.2.255
  • 192.168.2.1 (last octet will be replaced with 255)
  • 192.168.2 (will append 255 for the last octet)
  • 192.168.2. (will append 255 for the last octet)
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.
