PDW is a Microsoft Windows printer driver for the Raytheon TDU-850
hardcopier. It provides a previously unavailable linkage between this
printer and IBM PC compatibles running Microsoft Windows. This driver
supports all the text and graphics features normally found in other laser
printer drivers.
The user can ensure true WYSIWYG (what you see is what you get) compatibility
between the on-screen display of high-end application programs and
the final hardcopy image because PDW supports the unique Microsoft Windows
operating system requirement that printer drivers assist in the drawing
of graphical objects on the video display as well as on the hardcopier.
PDW
can be called upon by the Windows Graphical Device Interface (GDI) to draw
graphical objects (circles, lines, etc.) directly to the hardcopier or to
render graphical objects to shared memory so that the objects can then be
copied to the video screen by the screen driver. This allows Microsoft Windows,
in conjunction with the screen driver, to provide maximum WYSIWYG fidelity
while a document is being composed whenever PDW is selected.
PDW can
reside simultaneously on up to three separate PCs, each attached to a single
Raytheon printer utilizing the printer's standard IEEE-488 (GPIB) interface.
PDW contains special software to check for bus contention before
attempting to access the printer.
PDW carries the NASA case number MSC-22444. It was originally released as part of the NASA COSMIC collection.
