BASIC CONCEPTS
Print density Full throughput estimates are based on pages with an average
print density of approximately seven percent of the page. Pages
which are very dense require more time to image and to print.
Highlight color The LPS running V3.8 Color Compatibility Release or XDDI
software is compatible with the 4850/4890 printer running V3.7,
V4.0, or V5.0 highlight color software. Highlight color
applications can be printed when using V3.8 or XDDI software on
the LPS. Highlight color datastreams are fully supported and
translate to black and shades of gray.
Color text printed over a solid black background or vice versa,
disappear when printed on the LPS. There is no error message
when this occurs. Light tints with isolated single pixels may not
print on the LPS.
Form origin
All forms data described by FDL commands is positioned relative
to a point called the “form origin,” as shown in figure 1-9. This
point offsets from the virtual page corner by horizontal and
vertical displacement values, which you specify using the GRID
command. If none are specified, standard default values are
used to establish the form origin.
If variable data is merged with the form, set the form origin to
coincide with the beginning position of the variable data so that
the form and variable data coordinate accurately. Standard
computer printing formats are stored on the system. Refer to
the “Predefined formats” section, later in this chapter.
