Note
Some HP printers, such as the LaserJet 4L, 5L, or 6L
printers, do not support printer language switching or job
separation. See Appendix A for feature support information.
Using PJL, software applications can request information
such as printer model, configuration, and status. PJL also
can be used to change control panel settings and modify the
message displayed on the control panel, or change feature
settings in printers without a control panel, such as the HP
LaserJet 6L printer. For those printers supporting more
than one printer language, applications can print one job
using PCL, and then print the next job using PostScript or
another printer language—without any operator
intervention.
