I am using WMI with C# to enumerate and modify the printers on my computer.
I'm running Windows 7, and everything is working fine when I try to modify printers that are installed "classically". By "classically", I mean that the printer is just using a basic TCP/IP Port. I can rename it, set it as the default printer, etc. using the documented WMI functions here: http://msdn.microsoft.com/en-us/library/windows/desktop/aa394363(v=vs.85).aspx.
However, by default Windows is installing my printer as a WSD (Web Services on Devices) printer. When this happens, the printer uses a WSD Port, which I can't seem to touch using WMI.
In the screenshot below, you can see that my printer is using a "WSD Port". Below that port is the standard TCP/IP Port that my printer uses when installed without WSD.
The software that came with my printer installs the printer using a standard TCP/IP port. However, when I manually install my printer, Windows chooses the WSD port.
WMI seems to have no definition for WSD enabled devices. Does anyone know if this is true?
It should be in your WMI, all printers shown in your Devices and Printers are listed on WMI. To give you an example I have a similar situation where I have a printer using the WSD portname and we can manage it from code.
