USING THE CONTROL PANEL
2-22
The Parallel Setup submenu contains the following selections:
❐ Personality
❐ Bi-Direction
Personality Selection
You use this selection to specify the language interpreter mode for the parallel
port. The options are as follows:
❐ PCL ❐ Auto Sense
❐ TIFF Raw Mode ❐ PS (PostScript      )
❐ Hex Dump ❐ PS TBCP
The Auto Sense, PS (PostScript      ) and PS TBCP options display only when
the PostScript  option is installed. PS TBCP (Tagged Binary Communications
Protocol) is a binary format used by PostScript

.
Note: When Parallel or NIC Personality is set to PS (PostScript  ), the printer
will not be able to interpret PJL commands. If you use the PostScript 
driver, Parallel or NIC personality should be set to Auto Sense.
TIFF Raw Mode supports printing of TIFF files with no PJL commands
included in the print file.
Hex Dump prints the print file as hexadecimal data instead of interpreting
and formatting the print data. This is used for error analysis of the print
file.
The default value is PCL. However, when the PostScript  option is installed, the
default value is Auto Sense.
