NetworkDiscovererSubnetSearch Method (DiscoveryHandler, String)

Sends a discovery packet to the IPs specified in the subnetRange.

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

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).
subnetRange
Type: SystemString
The subnet search range.
Exceptions
ExceptionCondition
DiscoveryExceptionIf an error occurs while starting the discovery (errors during discovery will be sent via DiscoveryError(String).
Remarks
Subnet searches are defined by the first three subnet octets, followed by a range, such as 192.168.2. This method accepts IP addresses of the form, assuming a subnet of 192.168.2:
  • 192.168.2.254 (will send a discovery packet to 192.168.2.254)
  • 192.168.2.* (will send a discovery packet for the range 192.168.2.1 - 192.168.2.254)
  • 192.168.2.8-* (will send a discovery packet for the range 192.168.2.8 - 192.168.2.254)
  • 192.168.2.37-42 (will send a discovery packet for the range 192.168.2.37 - 192.168.2.42)
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.
