OVERVIEW
Page segments 
Page segments can consist of any combination of text data,
image block data, graphics block data, or bar code data.  Page
segments are different from overlays in that you store them
without printing instructions regarding the typestyle and page
position.  
Page segments are dependent on the page environment in that
they merge with the logical page acquiring its characteristics.
The typestyle for the page segment is the same one used when
printing occurs.  You can place page segments at any position on
the page as long as all elements fall within the VPA.

Note:  You cannot include other page segments or overlays
within page segments.
Images and graphics 
You can send illustrations, such as charts, complex line drawings,
and schematics to the printer as graphics, IM images, or IO
images.
Images
You create images by specifying individual points on the page.
The points are called picture elements, or pels.  Using an all–
points–addressable system, each square inch on the page
contains 300 by 300 points you can address.  Because of the way
they are created, each figure or image can require a large
quantity of data.
IM images are based on Advanced Function Printing Data Stream
(AFPDS) image cells.   IM images are uncompressed raster data
images, which are stored in your printer.
IO images are based on Image Object Content Architecture
(IOCA).  IO images are raster data images you can compress.
Compressed images reduce the amount of data sent to the
printer to create them and speed up transmission time.  You can
scale IO images to correct differences that may occur in the
resolution of the scanner as compared to the printer.
Graphics
You create vector graphics using individual lines, arcs, and
markers to identify a specific location in a graphic.  You can
create complex graphics using a minimum of data because only
the control information, such as the end points of a line, are sent
to the printer.
