H-P LaserJet+ Emulation mode is a command emulation mode: most of the H-P
LaserJet+ commands are accepted by the LaserWriter IINTX. This does NOT
mean that the output will always duplicate exactly the output from an H-P
LaserJet+.
While a command may be accepted, the output will be calculated and performed
by the same line-drawing routines and functions used when PostScript
commands are printed. The LaserWriter IINTX is not optimized for the H-P
LaserJet graphics commands.
This difference may cause problems with MS-DOS programs that require
H-P LaserJet+ graphics precision. For example, with a bar-code printing
program, the lines may not meet the exact tolerances (width or size) of
the H-P LaserJet+.
In H-P LaserJet+ emulation mode, the LaserWriter IINTX is not as fast as
in PostScript mode, because graphics must interpreted by PostScript. In
addition, In H-P LaserJet+ emulation mode, the LaserWriter IINTX is not as
fast as the H-P LaserJet+ itself.
