ESC/P-Specific Variables
The following table lists the currently defined ESC/P-specific variables
which are valid only for HP LaserJet 4PJ and 4LJPro printers, and
optionally for HP LaserJet 4V and 4MV printers. These variables can
be set using the LPARM : ESCP option. Note that HP LaserJet 4PJ,
4V, and 4MV factory defaults for these variables are in parentheses.
Note If ESC/P is installed in HP LaserJet 4V and 4MV printers and a menu
reset or cold reset is performed, the printer defaults to
FONTNUMBER = 0, FONTSOURCE = I, SYMSET = ROMAN8 and
PERSONALITY = AUTO. To re-establish ESC/P as the default
personality, set ESC/P as the default personality using PJL or the
control panel (in Japan, users can send the ESCPDEF.PJL file).
To print Japanese via PCL using the MS Mincho or MS Gothic
typefaces, set the SYMSET to WIN31J, FONTSOURCE to the SIMM
slot containing the MS Mincho or MS Gothic font (usually M4), and set
FONTNUMBER to 1 for MS Mincho or 2 for MS Gothic. Also set the
personality to AUTO or PCL. (Alternatively, in Japan, users can
configure the printer for PCL using the PCLDEF.PJL file.)
