The UNDERSIZE parameter determines the threshold for rounding the selected media size up to a
standard paper size. If one of the dimensions standard media size's printable area is smaller than the
corresponding dimension of the image (see MARGINxxx parameters for a definition of printable area of
a media size) by less than the percentage stored in this parameter, then that dimension is said to be
within the undersize margin capture zone. The parameter takes on an integer percentage ranging from
0 to 100%. The default value is 2%.
If both dimensions are captured in one of the undersize or oversize margin capture zones of a media
size, then the media size "captures" the image and the media size is selected. Note that this capture
zone concept applies only to standard sheet sizes, not roll sizes.
Mathematically, the capture zone concept can be described by the following equation:
Where undersize and oversize represent the percentage values in the undersize margin and oversize
margin parameters, respectively. MediaSizeDim and imageDim represent a corresponding dimension of
the candidate media size and the image size, respectively.

5.1.7.2.45 USEMARKEDAREA
When PAPER is set to a value for auto size detection (ANY, ANY_ANSI, ANY_ARCH, ANY_ISO, or
ANY_JIS), then this parameter determines whether the size of the image used to determine paper size
and image placement is taken from the actual bounding box of marks on the page (ON), or specified by
data format dependant page size commands if available (OFF).
An example of a page size command is the PS command in HPGL/2. If this parameter is OFF, then the
PS command arguments will specify the size of the image, even in the bounding box of the actual image
is larger or smaller. Setting this parameter to ON effectively overrides the PS command's sizing with
the image's bounding box. Recall that the PS command also specifies a clip window for the page. This
functionality is NOT overridden by this variable.
The set of possible values is ON or OFF. The default value is OFF so that the job will specify the
intended page size if this information is available.
5.1.7.2.46 VECTORHALFTONEOPT (new for V8, this is now a page parameter)
This parameter allows the user to optimize halftoning vector graphics based objects. There are two
values currently: LINE and AREAFILL. When LINE is selected, fine line rendering is prioritized in the
screening methodology. Fully stochastic screens are selected to reduce the amount of "aliasing" in the
screens with the relatively small feature size of fine lines. When AREAFILL is selected, wide area fills
(polygon fills) are prioritized. A more even clustered dot halftone screen is utilized to provide a uniform
filled area. This parameter does NOT affect image or raster data halftoning operations. The factory
default value is AREAFILL.

5.1.8 Printer State Class

This class of parameters actually record the state of the printing system. Three groups are defined to
specify the state: the Marking Engine, Media, and ESS Groups.

5.1.8.1 Marking Engine Group

The current state of the marking engine is encoded in this state variable group.
