How to determine if printer is xps ? c#

Question

How to determine if printer is xps? I found way to get property "Published" from wmi (it set to false if device is not physical), but i want to determine if printer is xps writer. Thanks

Answer 1

Printers are defined by the driver they use, not their name, so an XPS printer will use the driver Microsoft XPS Document Writer. This will be a reliable test until a third party creates another XPS print driver with a different name, which I don't expect to happen anytime soon, if ever.

Answer 2

If you detect from CPrintInfo class, printing to XPS file returns following values -

CPrintInfo::m_pPD->GetDriverName() returns "winspool"
CPrintInfo::m_pPD->GetDeviceName() returns "Microsoft XPS Document Writer"
CPrintInfo::m_pPD->GetPortName() returns "XPSPort:"

So, it might be safe enough to assume if it is XPS or not by checking device name and port name.
