Use of International Standards Organization Document Printing Application
Filter for Dynamic Printer Support Selection

      Disclosed is a method of using the International Standards
Organization Document Printing Application (ISO DPA) 10175 standard
filter mechanism, which was originally intended only to filter
attributes returned from an object query, to specify the selection
criteria for a printer device support system.

      The main feature of this method is the definition of an
attribute which extends the ISO DPA 10175 standard:
id-att-device-support-select-criteria.  This server attribute is
multi-valued, each value consisting of a pair:
      { device-support-system-OID, selection-filter }

      The first field of the pair uniquely identifies a device
support system.  The second field gives the selection criteria used
to determine whether or not to use that system to support a new
printer being created.  This selection-filter uses the ISO DPA 10175
filter syntax and underlying support.  The filter is specified as a
string that is evaluated against the new printer's set of attributes
to determine if a printer with the those characteristics should be
managed by that device support system.  Normally, a filter is
evaluated against a set of attributes returned from a query to
determine if the requester wants to see those attributes.  In this
method, the same filter syntax and underlying support is used to
select or not select a a device support...
