The
LaserJet
printer
is
a Level III printer, meaning that all
applications written
for
Level
I,
II,
and III printers will operate
correctly
on
LaserJet
with
no
modification. The LaserJet+ and
LaserJet
500+
printers
are
level IV printers, meaning that all
applications written
for
Level
I,
II, III,
and
IV
printers will
operate
correctly
on
LaserJet+
and
LaserJet
500+
printers with
no
modification.
All
LaserJet
family printers support the following features, in
addition
to
the standard Level III features, which take advantage
of
some
of
the
printer's unique capabilities:
• Line termination
• End-of-line wrap-around
• Portrait/landscape orientation
• Select number
of
copies
•
Paper
input control
Applications written using these additional features may not
operate
as intended
on
other
Hewlett-Packard printers which
do
not
have these capabilities.
