Printer Reset
Hewlett-Packard strongly recommends the use of both the
E
C
E
command and the
E
C
%–12345X
command (Universal Exit
Language/Start of PJL — also referred to as the
UEL Command
)
at the beginning and end of each job. (The order of these commands
is critical; refer to Table 24-1 for an example.) This allows the next job
to start with the default settings as a known base. Starting with the
default environment at the beginning of each print job eliminates the
need to set every feature each time a job is run.
Note
The UEL Command (
E
C
%–12345X
) has the same effect as the
E
C
E
command, and also enters PJL Mode of operation for printers that
support PJL. The
E
C
E
command should be included to ensure
backward compatibility (the UEL command is ignored if received by a
printer that does not support PJL).
Do not perform a printer reset
within
a job.
