HP LaserJet 1100 Series Comments
The HP LaserJet 1100 series printers have a PJL feature set very
similar to the HP LaserJet 6L printer. Listed below are some of the
differences.
The INFO VARIABLES command returns the number of pages
that have been copied, printed, and scanned
(COPYPAGECOUNT, PRINTPAGECOUNT, and
SCANPAGECOUNT).
For the LaserJet 1100 series printers, the RESET command
does not initialize the PAGECOUNT, SYMSET, and PAPER
variables. Instead, it sets the current value equal to the stored
default value.
When a SET or DEFAULT command is used with the
AUTOCONT or DENSITY variables, the User Default and PJL
Current Environment settings are not modified as they are on
most LaserJet printers.
For the LaserJet 1100 series printers, the INITIALIZE
command does not reset the PJL variables stored in NVRAM
back to the factory values. It sets their current values to the
stored default values (see the following paragraph).
The HP LaserJet 1100 PJL variables can be set to factory
values by performing a control panel NVRAM INIT. This is
done by holding down the control panel button and cycling the
power. When the power comes on, continue to hold down the
control panel button. The LEDs will flash briefly when the
power comes on, and then will go off. Hold the button down
until the LEDs cycle once, then release the button.
