PERSONALITY Personality for implicit switching (implicit
switching refers to switching to the
default personality without explicitly
doing so with the @PJL ENTER
command). Note that the value string
(PCL, POSTSCRIPT, and so on) for
each installed personality is defined by
the personality itself. If the AUTO option
is selected, and a job is sent without an
ENTER LANGUAGE command, the
printer looks for context clues to
determine which personality takes
effect (except in the case of ESC/P,
which cannot be selected using context
switching). When the personality is
changed, memory is reconfigured and
all downloaded fonts, PCL macros, and
PostScript dictionaries are lost
(however, no I/O data is lost). Refer to
Appendix A, “Commands that Affect
Printer Memory.”
For the LaserJet 4PJ, this variable is
assigned on a per-port basis (see
“Port-Specific Variables”).
For the DeskJet 1200C, setting this
variable to INSTALLED causes the
printer to select the default personality
from those available. It selects from the
available optional personalities before
resorting to those available on a
standard printer. Reading back the
variable identifies the selected variable.
