graphics presentation space window
You can specify a part of the presentation space to be
mapped to the graphics block. This portion is called the
graphics presentation space window. Specifying a
window is synonymous to cropping or trimming.

downloading overlays, page segments, and/or fonts.
After the printer prints the page, the printer returns to the
home state.
host assigned ID The host assigns an ID to every resource (page segment,
overlay, or font). These IDs are used for loading and
calling.
host computer The computer that stores, processes, and sends data to
be printed, and which communicates directly with the
printer. The term "host" indicates the controlling
computer, since modern printers are themselves
microprocessor-controlled computer systems.
image An illustration or picture. Differs from graphics.
image block Rectangular space that has a specified size, position,
and orientation on a logical page. The image block
contains the image. It is the area where the image
presentation space is mapped to.

Rectangular, conceptual space where an image is
generated. It is mapped to the image block. Once
mapped, the image is ready to be printed.
initialization A series of processes and self-tests to set power-up
default conditions and parameters.
interface The hardware components used to link two devices by
common physical interconnection, signal, and functional
characteristics.
invoke To put into effect or operation.
IPDS Intelligent Printer Data Stream. Allows sophisticated
printing, such as merging text and graphics.
Abbrev. for lines per inch. A measurement indicating the
lpi
vertical spacing between successive lines of text. For
example, 8 lpi means 8 lines of text for every vertical
inch.
logical page A rectangular area on a physical page. The logical page
has a specified size, orientation, location, and offset. The
logical page is the area where bar code blocks, image
blocks, graphics blocks, and text is printed. Printing
occurs in the area common to the physical page and the
logical page.
logical link The parameters that specify data transfer, control, or
communication operations.
