Jay,
In order not to mis-lead the reader or bend the other groups working
on scanning and faxing out of shape, lets add something that indicates
that support of these other devices is outside the scope of the current
MIB, but that this MIB can be used with extensions for other devices.
We, at Xerox, have been using our private job MIB for both scanning and FAXing
as well as printing and have found no problems with doing so. Only a few
additional attributs are needed for such (either in the same MIB or in
an extension MIB that augments the job MIB). All of the objects and many of the
attributes are just as applicable to scan and fax jobs as printing jobs.
Here is the last part of the Abstract:
This MIB is intended to be implemented (1) in a printer or (2) in a server
that supports one or more printers. Use of the object set is not limited to
printing. However, support for services other than printing is outside the
scope of this Job Monitoring MIB. Future extensions to this MIB may
include, but are not limited to, fax machines and scanners.
So how about the following devinition for "device":
Device: A hardware entity that performs one or more document
transformations between electronic and/or hardcopy forms. Use of the object
set is not limited to printers. However, support for services other than
printing is outside the scope of this Job Monitoring MIB. Future extensions
to this MIB may include, but are not limited to, fax machines and scanners.
