Hi Konstantin,

WONDERFUL NEWS that Ricoh is implementing the CIM Printer classes!
- more on this topic later in this note.

Apologies for my delayed response - traveling since last Wednesday.

Sadly, there is NOT a property for Vendor Name, because the CIM Printer
classes are derived *directly* from the Printer MIB v2 (RFC 3805) which does
not have such a property (prtInputVendorName was not modelled in the
CIM_PrintInputTray class because it is NOT widely correctly implemented).

In MIBs, Vendor Name belongs as part of sysDescr in MIB-II (RFC 1213).
I can't find this in existing CIM classes either (odd?).

However, in order to add vendor-specific properties, you will probably
subclass the standard classes, in which case vendor name WILL be
explicit in the CIM_LogicalDevice.CreationClassName property - Rick
Landau (Dell, CIM Core co-chair) assures us that this subclassing is
typical across most CIM implementations.

The Ricoh implementation, along with Rick Landau's complete prototype
of all CIM Printer classes (now nearing completion) will satisfy the CIM
rule that two independent implementations are required to move a new
class (or new property) from CIM Experimental (backwards compatibility
NOT guaranteed) to CIM Final (stable and backwards compatible).

We will talk about this (Ricoh and Dell implementations) during this week's
PWG Face-to-Face here at Samsung in Irvine, CA on Thursday.

Please feel free to ask any questions - as co-editor with Rick Landau of
the CIM Printer classes, I'm *very* interested in helping implementors.

- Ira

PS - Rick may have better advice, but he's at *another* conference
all this week and on vacation the rest of the year - but I'll leave him
voice mail on his cell phone.
