about CapabilityDescriptions

I have a HP LaserJet 5100 printer.I run the following script to receive its
capability description.
It is strange that I receive "color" capability description,though HPLJ5100
is a black and white printer.Why?

######################VBS################################
Set colPrinters=objWMIService.instancesof("win32_printer")
For Each objPrinter in colPrinters
WScript.Echo "Device Name: " & objPrinter.name
CapabilityDescriptions= objPrinter.CapabilityDescriptions
For Each Capability In CapabilityDescriptions
WScript.Echo Capability
next
next

Hi,

That string is just a free-form return from the driver. I'm not sure why
the driver is returning color when it's B&W but it sounds like an issue with
the driver not WMI.

There is also Win32_PrinterConfiguration.Color property, maybe it returns
correct values.

urkec:
Win32_PrinterConfiguration.color is not able to return the correct color
description either.

You say it is related with the printer driver. It sounds correct. In the
test-printing page, however, I can see " support color: no ",while
Win32_Printer.CapabilityDescriptions return "color".
Is it strange, isn't it?
