>>Media Orientation: All Finishing Operations are defined relative to a
>>portrait orientation of the medium, regardless of the orientation of
>>the printed image. The 'X' and 'Y' axis, therefore, will always
>>reference the medium as shown in figure 1. All edges and corners are
>>also defined with the medium orientation as shown using the syntax
>>upper, lower, left, and right. Thus the lower edge of the medium is at
>>Y = 0, the left edge is at X = 0, and the lower right corner is at
>>(X1, 0) as shown in the figure.
>>
>>Finishing: Defined by DPA as an operation on a document following the
>>completion of the image process and prior to the delivery of the
>>document into the output subunit. Finishing operations defined within
>>this document are those applied to one or more instances of rectagular
>>paper sheet media.
>>
>>Finishing Operation: Defined by DPA as a process applied by a machine
>>such as trimming a document, folding the sheets in a document, and
>>applying a binding to a document.
>>
>>Finishing Specification: Defined by DPA as the specific sequence of
>>operations for a serial combination of finishing operations. The
>>exact sequential order of the operations, in many cases, is critical to
>>the obtaining the desired result. For example, a folding operation
>>followed by trimming could provide a very different result than if the
>>trimming was followed by the folding.
>>
>>Finishing Operation Parameters: This parameter set is used to create a
>>detailed definition of the finishing operation. Generic Finishing
>>Operation Parameters are applicable to any Finishing Specification.
>>
>> Head Mechanism: Defined by DPA as the physical mechanism that is
>> used to perform a finishing operation. The head position may be
>> fixed or variable depending upon the capabilities of the device.
>>
>> Reference Edge: Defined by DPA as the edge of the document relative
>> to the axis to which the finishing operation is applied. The edge of
>> the medium defined to be the Reference Edge may be either the 'X' or
>> the 'Y' axis, depending upon the finishing operation to be performed.
>>
>> Finishing Operation Axis: Defined by DPA as the axis to which some
>> finishing operations are applied to or referenced from by the Head
>> Mechanism. An example is the axis for a fold operation.
>>
>> Head Locations: Defined by DPA as the position of the Heads on the
>> Finishing Operation Axis.
>>
>> Finishing Axis Offset: The offset from the Reference Edge to the
>> Finishing Operation Axis at which the finishing operation takes place
>> or is applied.
>>
>> Jog Edge: Defined by DPA as one of the two edges that are
>> perpendicular to the Reference Edge. Specification of the Jog Edge
>> parameter implies that the edges of all the sheets that correspond to
>> the referenced edge coincide.
>>
>>Two-Stage Finishing: DPA defines this process as sequences of explicit
>>finishing operations to be applied on two stages. The first stage
>>operations are applied to each document within a job that contains
>>several documents. The second stage operations are applied to each set
>>of documents that compose a complete job copy.

>>NEW ATTRIBUTES RELATED TO ABOVE:

>>finishingOperationOffsetUnits(9), INETGER
>> INTEGER: An enumeration which defines the units of measure for the
>> attributes finishingOperationAxisOffsetX and
>> finishingOperationAxisOffsetY. The enum values for this attribute
>> are defined by PrtMediaUnitTC.
>>
>>FinishingOperationAxisOffsetX(10), Integer32
>> INTEGER: Defines the offset of the Finishing Operation Axis from the
>> Reference Edge on the 'X' axis. The units of measure are defined
>> by the attribute finishingOperationOffsetUnits.
>>
>>FinishingOperationAxisOffsetY(11), Integer32
>> INTEGER: Defines the offset of the Finishing Operation Axis from the
>> Reference Edge on the 'Y' axis. The units of measure are defined
>> by the attribute finishingOperationOffsetUnits.
