Menu Administration/Emulations/PostScript/Emulation Level
Choices Level 2—For PostScript Level 2 files and most Level 1 files.
Level 1 B/W—For files that contain only black-and-white
PostScript Level 1 operators. This mode does not support
the PostScript color operators; the use of color operators
could cause the print job to fail.
Level 1 Color—For files that contain color PostScript Level 1
operators. This mode accepts color PostScript Level 1
operators and translates these commands to the
appropriate grayscale. This is the recommended setting for
Level 1 compatibility since it contains all of the commands
in Level 1 B/W and the color commands.
Default Level 2
Notes In general, we recommend that you use the Level 2 option.
Use the Level 1 B/W and Level 1 Color options only if you have
files prepared in an application which is not fully compatible
with Adobe’s PostScript Level 2 page description language.
