Namespace: Zebra.Sdk.Printer.Discovery
Assembly: SdkApi.Core (in SdkApi.Core.dll) Version: 3.0.3271
Syntaxpublic static void FindPrinters( DiscoveryHandler discoveryHandler, List<string> printersToFind, int waitForResponsesTimeout )
Parameters
- discoveryHandler DiscoveryHandler
- A DiscoveryHandler instance that is used to handle discovery events (e.g. found a printer, errors, discovery finished).
- printersToFind ListString
- A list of IP addresses or DNS names for the printers to be discovered.
- waitForResponsesTimeout Int32
- Time to wait, in milliseconds, before determining that there are no more discovery responses.
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 wait up to waitForResponsesTimeout milliseconds determining that there are no more discovery responses.
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.
