Description
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
"Commands that Affect Printer Memory" in
Appendix A.
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.
