Enable WSPrint 2.0 on a device

  • Artikkeli

This topic describes the settings required to enable WSPrint 2.0 on a device.

Broadcast a Mdns printer service

This must be done using the service type of PrintService._printer._tcp.local on port 80.

Implement a HTTP endpoint

The endpoint needs to be able to respond to WSPrint 2.0 operations. You do not need to perform SOAP validation and processing. You can instead use string detection and replacement.

Once the WSPrint endpoint is functioning, you need to customize the XML returned from the GetPrinterElements call with a custom device id:

<wprt:DeviceId>MFG:MS3D; CMD:XPS; MDL:Compat; CLS:Printer; DES:Compat; CID:MS3DWSD</wprt:DeviceId>

This matches with the Compatible ID in the published INF:

WSDPRINT\MS3DCompatE2D2
