to support bi-directional communication between printer and computer.
PCONSOLE
A NetWare utility that can be used to create, configure, monitor, and manage
queues in a NetWare server, and to attach print servers to the queues.
PDL
An acronym for P age- D escription L anguage. This refers to a programming
language, such as PostScript, that is used to describe output to a printer or a
display device, which then uses the instructions from the PDL to construct text and
graphics and create the required page image.
Peer-to-Peer

Windows for Workgroups, NetWare Lite, and Macintosh System 7 are examples of
peer-to-peer networking products.
Print driver
